Effective way to determine Linux's sda/hda disks and partitions equivalents in Grub4dos

November 15, 2016, 11:20 am

Pretty much as the title says, I am wondering what is the most effective way to determine Linux's disk/partition tags from grub4dos counterparts, like for example:

  • (hd0,0) = sda1
  • (hd0,1) = sda2
  • (hd1,0) = sdb1
  • (hd1,1) = sdb2

 

The partition number is easy because it's simply the same partition number +1.

But the disk number/letter isn't so and seems to only be determinable using nested "if"s.

 

At the moment I'm using something like this:

# Determine Linux disk/partition id - set LXDSKTYP to use hd instead of sd if using IDE disk
set LXDSKTYP=sd
find --set-root /target/file.ext
if exist /target/file.ext set DSKN=%@root:~3,1% && set PRTN=%@root:~5,1%
if %DSKN%==0 set LXDSK=a || if %DSKN%==1 set LXDSK=b || if %DSKN%==2 set LXDSK=c || if %DSKN%==3 set LXDSK=d
if exist PRTN set /a LXPRTN=%PRTN%+1
if exist LXDSK set LXDSKID=%LXDSKTYP%%LXDSK%%LXPRTN%

Due to my limited knowledge of Grub4dos and it's extensive range of possibilities, I wonder if a better approach is possible, particularly for determining the disk letter.

 

Thanks for your input ;)

How to boot a dmg image?

Hello,

 

I need some assistance in regards to booting mac os dmg image from grub4dos.

 

My USB currenltly has 2 primary partitions: 1st: 137GB, and 2nd is 107GB. The USB itself is a USB-to-SATA bridge, and all partitions are seen as fixed.

 

I know this may be possible with Easy2Boot but I am reluctant in using it because I'll have to change my whole file structure, curretnly being groupped into iso, img, flp etc.

Or if I have to Easy2Boot, could someone teach me how to use while still using my grub4dos version and menu.lst? I'd like to keep my current grub4dos menu.

 

Thank you

grub4dos batch file converts @root drive to Linux equivalent

November 17, 2016, 11:44 am

Some Linux kernels accept a boot parameter/cheatcode that say "boot from this drive/partition", but how do you get a Linux drive name in a grub4dos menu?  Place this grub4dos batch file where it can be called from your grub4dos menu.lst:

!BAT
# root2lin.g4b grub4dos batch file by Mythenadia
# Returns @root drive/partition in linux format
# e.g. (hd2,18) in grub4dos becomes sdc19 in linux
# Handy for passing @root as a linux kernel parameter
# Works for 26 drives, but could easily be expanded
# Remove or alter the echoed "sd" prefix if necessary

debug off
setlocal
set /a drv=*0x82a0&0x1f
set /a prt=*0x829e&0xffff+1
call :substr abcdefghijklmnopqrstuvwxyz %drv% 1 | set drv=
echo sd%drv%%%prt%
endlocal
debug normal
exit

:substr
# Generic substring routine where input, start, length can all be variables
# Result goes to stdout, or can be piped to another command
# Typical usage example:
#   call :substr input start length | set output=
#   set /a output = %output%
setlocal
set input=%1
echo %input:~%2,%3%
endlocal
exit

Here's an example of how to use root2lin.g4b in a grub4dos menu.lst:

...
title Porteus 3.2 XFCE\n Booting Linux from beyond partition 15 test
find --set-root --ignore-floppies --ignore-cd /porteus/porteus-v3.2-i586.sgn
call (bd)/root2lin.g4b | set disk=
kernel /boot/syslinux/vmlinuz from=/dev/%disk% changes=/porteus noauto
initrd /boot/syslinux/initrd.xz
...

Yeah, I know you can write a batch file to memory in a grub4dos menu, then run it with initscript, but I couldn't figure out how to pass any parameters that way.

 

Don't know if this would be useful to anyone else, but I thought I'd share it just in case.

Cheers,

Mythenadia

Anyone care to explain the name "GRUB4DOS"?

November 22, 2016, 3:45 am

So.....what's the meaning behind the name? GRUB/GRUB2 started in the Linux community, DOS with Microsoft. Why create something that is seemingly the unholy union of 2 exact opposites (and enemies, by some accounts)? I assume it is based on original GRUB rather than GRUB2. Is it GRUB "for" DOS, as the 4 implies? So basically, GRUB repurposed to work in a DOS environment, with a focus on Windows?

 

Why is it not UEFI compatible? With things moving more toward UEFI and GPT, what is G4D's significance (or relative lack of usefulness in anything other than legacy BIOS/MBR)?

 

What makes G4D better than something like Syslinux or GRUB2? Scripting? Is it more flexible? Can boot a wider variety of stuff (mostly OSes or tools/utilities)?

PassPass - Bypass the Password

November 26, 2016, 11:27 am

Meet PassPass (Bypass the Password), a nifty Grub4DOS batch script to disable/re-enable Windows logon password validation. The latest version supports both 32-bit as well as 64-bit versions of Windows XP/Vista/7/8/8.1. Credit (as well as dis-credit) is to be equally shared between Wonko the Sane and Holmes.Sherlock for the idea and coding respectively. We appreciate any success/failure report mentioning the following:

  • Windows version (e.g. XP, Vista, 7)
  • Service pack (e.g. SP0, SP1)
  • Architecture (e.g. 32-bit/64-bit)
  • msv1_0.dll version (e.g. 6.1.7600.16525) along with MD5 checksum, if possible

Technical Details: The script tries to locate all existing Windows installations and corresponding Windows editions as well. Thereafter, it replaces the CMP instruction responsible for password verification with a 'benign' sequence of bytes. For reverting back the changes, the process is just the opposite. The whole idea is derived from WindowsGate and Astr0baby's tutorial.

Usage:

  • Install Grub4DOS. You may prefer using RMPrepUSB. Script tested with Grub4DOS v0.4.5c-2013-03-03.
  • Download grubutils and copy WENV binary on the root of the boot media. Script tested with grubutils-2011-06-27.
  • Copy PassPass, PassPass.bak and menu.lst on the root of the boot volume.
  • Boot
  • Ideally 'Autodetect' mode should be able to list out all existing Windows installation. For buggy BIOS-es, try appropriate <Disk#> and <Partition#> to 'Forcedetect' Windows installations.
  • Choose either 'Patch' or 'Unpatch' respectively for disabling/re-enabling password verification.
  • Reboot and boot into target Windows.

 

Beta Testing:

  1. Download latest version of the script.
  2. Backup /<Windows directory>/system32/msv1_0.dll of target installation.
  3. Patch it.
  4. Test whether the patch is working by being able to log on with arbitrary password.
  5. Note MD5 checksum of the DLL.
  6. Unpatch it.
  7. Test whether whether unpatch is working by being not able to log in with all but correct password.
  8. Note MD5 checksum of the DLL.
  9. Compare the MD5 hashes.
  10. Success is defined by the patch working at step #4, unpatch working at step #6 and hashes matching at step #9.
  11. Report success/failure in the format mentioned above.

making 2003 usboot more universal by adding uncompressed DriverPacks

hi all,

im trying to figure out how i can add the uncompressed DriverPacks left by the DriverPacks BASE "Keep The Drivers" method from an existing XP installation into a 2003 installation.

first i tried copying the DriverPacks from the XP to the 2003 into the exact same place (C:/WINDOWS/DriverPacks) and copying the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\DevicePath string from the XP into the 2003 but this was not successful.

what am i missing? i thought that would work. other registry settings needed?

Im going back through Wimb's IMG_XP tool looking for more clues but if anyone knows how i can do this, please let me know.

this 2003 is 32bit, I used USBoot tool and installed EWF to make it bootable on USB flash, it boots on foreign hardware fine but must manually add drivers each time.

I'd like it to install drivers automatically like XP does but when I try to integrate the DriverPacks the same way as XP, it doesnt work do now Im trying to do it after installation.


surely its possible, but how?

thanks

Hello everyone,

 

I am encountering some issues with the network boot in one of our servers.

I use windows server 2003, on this server i have 3Com TFTP Server(TFTPCTRL.EXE), DHCP server and Symantec GhostCast Server 7.5 - we use this same configuration on other servers and do not encounter PXE-E55 error, i have tried to compare an error in configs without succes.

 

DHCP options are:

003 : Router

004: Time server

006: DNS server

012: Host name

013: Boot file size

046: WINS/NBT Node type

066: Boot server host name

067: Bootfile name

 

Client gets an ip adress after booting from PXE, also mask and DHCP ip is shown but afterwards PXE-E55 appears.

Any ideas?

PEPassPass is developed from Holmes.Sherlock's PassPass (Bypass the Password)  :thumbup:  
PassPass is a nifty Grub4DOS (BIOS) batch script to disable/re-enable Windows logon password validation.
 
PEPassPass is an AutoIt executable to disable/re-enable Windows logon password validation, too.
It is intended to be run from either Windows PE or from a second NT installation, if any, to patch the first one.
A possible use case is systems equipped with UEFI where Grub4DOS may fail to boot.
For such systems, one needs to boot either Grub4DOS, hence PassPass in Legacy/BIOS compatible mode, or Windows PE/second NT installation to boot PEPassPass from.
   
In short, an addition to the original PassPass, really much faster if Grub4Dos is available.
     1.boot to grub4dos, 2.patch the file, 3.continue booting your patched Windows OS.
PEPassPass is able to patch Windows XP/Vista/7/8/8.1 for both 32-bit and 64-bit versions.
 
PEPassPass.jpg
WinLogon.jpg
 
Technical Details:
The script tries to locate all existing Windows installations and corresponding Windows editions as well.
Thereafter, after changing permissions, it replaces the CMP instruction responsible for password verification with a 'benign' sequence of bytes.
For reverting back the changes, the process is just the opposite.
The whole idea is derived from WindowsGate  and  Astr0baby's tutorial
 
Usage:
PEPassPass.exe : displays the GUI, Select the OS drive and use buttons, Backup, Restore, Patch or UnPatch.
PEPassPass.exe /Source : Extract the embedded source in same folder.
 
Test:
   1.Download latest version and include in your WinPE, BIOS and/or UEFI.
   2.Backup /<Windows directory>/system32/msv1_0.dll of a target installation protected by password at logon.
      Backup file: /<Windows directory>/system32/msv1_0.dll.bak
   3.Patch it. The Backup file: /<Windows directory>/system32/msv1_0.dll.bak is created if not exist,
      Backup not done.
   4.Test whether the patch is working by being able to log on with arbitrary password or without password.
   5.Unpatch it.
   6.Test whether unpatch is working by being not able to log in with all but only with the correct password.

Ciao a tutti,
Vi scrivo perché ho bisogno d'aiuto per la risoluzione del seguente problema, relativamente al quale ho già trovato diversi post sul forum che tuttavia non mi sono stati d'aiuto. All'avvio, il pc rimane per diverso tempo sulla schermata iniziale (della scheda madre), per poi indirizzarmi su di una schermata (GRUB4DOS 0.4.5b) in cui mi compaiono tre opzioni (Spyhunter 4, Windows Xp, e Windows Vista/7) nessuna delle quali tuttavia, una volta avviata, risulta funzionante (find --set-root /sh4eldr/vmlinuz ; Error 15: File not found).
Ho letto online che questo problema emerge dopo avere installato e svolto una scansione con Spyhunter, cosa che però nel mio caso mi risulta piuttosto strana: Spyhunter l'ho installato diverse settimane fa a causa di un virus, per poi disinstallarlo quasi immediatamente - e se anche la disinstallazione "tradizionale" non avesse funzionato, credo che i file relativi al programma dovrebbero essere stati eliminati attraverso il ripristino di sistema, al quale ho optato a causa del malware stesso.
Un altro dettaglio: tempo fa ho compiuto l'aggiornamento da windows vista a windows 10, ma sulla lista di avvio non compare! Perché?
Mi sono chiesto se fosse un problema relativo all'hard disk, così ho controllato sul software della scheda madre (ASUS EZ Flash2) al quale posso accedere all'avvio, nel caso non riuscisse a rilevarlo, ma mi pare funzioni correttamente.
Dopodiché, ho controllato anche nel bios, e qui invece ho notato che l'hard disk su cui il sistema operativo è installato non viene rilevato (non compare in "boot device priority").

... Cosa posso fare?

Grazie in anticipo per le risposte,

Frankie_G

I have just downloaded the 64bit version of tftpd32 to my Windows 7 64 bit OS.

When I open it gives the error:  Bind error 10013.  An attempt was made to access a socket in a way forbidden by its access permissions.

 

The software will open once I click OK.  After a few moments the tftpd server tab disappears.  If I look in Services.msc the service is still running.

 

I don't have any firewalls installed and the Windows Firewall is disabled.  The only AV I am running is Security Essentials.  I have added an exception for the tftpd executable and the installation directory.  No luck - still get error.

 

Any ideas out there?  I Googled and this error turns up a lot of stuff but nothing I saw was related to tftpd32

 

Thanks.

Easy2Boot flash drive no longer recognized

I spent a fair bit of time setting up an Easy2Boot 64gb flash drive and it worked great for a while. But now, when I insert the flash drive into a Windows 7 system, I am prompted to format the drive in order to use it. When the flash drive is inserted into a Ubuntu system, it does not automatically mount (as it used to).

 

Is there any way to recover this E2B setup? Or should I start over? Any ideas on what might have caused this, so that I can avoid this issue in the future?
