Unfortunately at the moment you can only have standard reply #32:

unless you post LOTS more details on both your hardware AND software you used, and HOW you used it.

Here is a quick sum up:

about the proper way to ask for help.

I tried to boot without any hdd conected to motherboard and i have the same problem; could it be the bios too old? please look at the report! My usb it's made with WinSetupFromUSB 1.0 beta6 and i don't have problems with others computers.

The issue has nothing to do with WinSetupFromUSB or with the windows install.

It is something in the early boot phase.

WHAT tool did you use to partition/format the stick?

With WHICH options?

How big is the USB stick?

How big are the partitions?

Which filesystem(s) are used?

Best thing would be to get HDhacker:

get BOTH the MBR (first sector of \\.\PhysicalDrive) and the bootsectors of the partitions (\\:\LogicalDrive) , compress them together in a .zip and attach the .zip to your next post.

This time my usb stick has only one partition and that error is still present

to format the stick i used rmprepusb from winsetupfromusb 1.0 beta 6 with these options: boot at xp(ntldr) and ntfs filesystem with boot as hdd and my usb stick has 8 gb

I think you got the "wrong" disk. :ph34r:

If you created the MBR from hard disk 0, that is the FIRST hard disk, i.e. the one you booted from, and thus you can boot from the stick allright ;).

Seriously, the MBR is of a device that has a NTFS formatted Primary Partition 20,974,431,744 bytes in size and an Extended one 99,048,821,760 in size, that all in all looks like a 120 Gb hard disk.

The bootsector is probably correct, as it is that of a NTFS partition 8,011,389,952 bytes in size, that looks like possible for an 8 Gb stick.

This one seems like the "real" thing.

The DATA in it appears correct, it has a first partition which is the right size and offset as the bootsector and a second Hidden partition that is "normal" if you used RMPREPUSB with the the "Boot as HDD (C: 2 ptns)", CODE seems like some version of GRUB or grub4dos.

The "Missing MBR helper" comes from it.

If it's a grub4dos MBR, it will look for file grldr in root of the partitions.

If there isn't any such file, the message will be printed to screen.

Would it be possible that after the formatting by RMPREPUSB (which if you chose "XP/BartPE bootable (NTLDR)" should have written a "normal" Win2K/XP/2003 MBR) somehow the install on it of grub4dos (by WinsetupfromUSB) failed? :unsure:

Or that some other GRUB/grub4dos installing program was run on the stick?

(It doesn't look like the grub4dos MBR that winsetupfromUSB uses AFAIK)

What I would do if I were you is the following:

  1. get MBRFIX:
    http://www.sysint.no/nedlasting/mbrfix.htm
    http://www.sysint.no/products/Download/tabid/536/language/en-US/Default.aspx
    open a command prompt, and in it run:
    MbrFix /drive <num> fixmbr
    (the correct <num> shoud be 2 if your last posted file is named "correctly")
  2. then copy to the stick:

[*] try to boot from the stick, if you can see the two choices, it means that now the stick is OK

[*] if it is OK, you can try running again WinsetupfromUSB, and see if it recognizes the USB stick without need to repartition/reformatting it
