USB IMAGING ADVICE RMPREP
Posted 19 August 2010 - 12:19 PM
WHen using RMPrepUSB it install grub4dos onto the MBR, but you can install it onto the partition boot sector using
WARNING: This assues your USB drive is PhysicalDrive 1. You will need to change the 1 to match your USB drive number - don't use 0 or you will trash your HDD!
So format using RMPrepUSB MS-DOS option, FAT32 - then go to command prompt and run grubinst from RMPrepUSb folder (as admin) using above command.

USB is physdisk 1 so OK with that command -:_00

2. MSDOS prepared ( NO OVER-RIDES FIRST) was gonna add one back at a time "if" it failed (if? you mean......... ......)
3. Admin CMD, cd to my RMPREP folder, ran "grubinst (hd1,0)".
4. Made sure it had been taken with a qemu USB boot. G4D loaded OK.
5. Went to PROBLEM computer and "We have a grub4dos" menu!!
It's booted off a stick. I am so chuffed. You legend!
So now going forward.....
1.) But what does this mean?
2.) If I made my sticks booting from the partition, should they still be compatible with others? Should have thought so.
3.) I think then my image that "miraculously" works could have been prepared using grubinst (GUI That I used to use) and I selected the partiton (PBR) instead of MBR. These are back in the day before I realized RMPREP was my one stop shop for all my booting needs.
I'm so happy! Looking forward to your views on this headache cleansing REEEEEZULTAH!

1. Use RMPrepUSB to format as MSDOS as before
2. Use RMPrepUSB to install grub4dos (the clue is in the name)

I will do a new Beta tonight for you...
What if you RMPRep as WinPE v2 (bootmgr) and then use grubinst (hd1,0) command line (or does it have to be MSDOS format) ????

Just got home so cant test the latest part, but will do it first thing.
Does PBS grubinst, still offer good booting as opposed to MBR. i mean can some machines behave funny if G4D sits in the PBR
as opposed to the MBR. Just curious?

maybe some should try and ask the grub4dos inventors aswell? who knows them/him/her?

grubinst says it has worked when I launch the app from inside RMPrepUSB, but it does not actually write any sectors!!! The same command executed in a cmd shell window manually works fine. There is something going on with volume locking but I just cannot get it to work. I even created a .cmd file and then executed that by calling it from RMPrepUSB but even that does not work (though grubinst reports it did work!).
No problem writing MBR as Win7/Vista lets anyone write to MBR (just not PBR or inside a volume!).
Is grubinst 1-1-2008 version the latest???
Have to get some shut-eye now. Maybe have more success at weekend...

I did the test and using the BOOTMGR option and writing the code to PBR also booted on the trouble machine!
I am on XP pro here at work (admin) and I had to run this twice before it took the g4d.....
edit seems like 01-01-2008 is latest?

on my 32 gb I just re made it (there's another prob I posted under tool thread unrelated to this though) I found more interesting info.
On the problem machine my 32gb would hang the PC just before boot menu came up, I could then pull out the stick, wait a second, then the menu would appear, then I could plug USB back in then boot fine. A little quirk I could live with.
As mentioned I just re made the 32gb stick; formatted, recopied the data and then made bootable with the command line in question at the mo; "grubinst (hd1,0)"
Now on the problem machine, no hanging of any description, boots perfectly now!

Only issue is that grubinst does not seem to be able to update an NTFS PBR but can update FAT16/32 PBRs under Vista/Win7.
