China DOS Union

Under Windows 2003, I modified boot.ini in ntldr to change it to XXXX.ini, then renamed ntldr to cylc, and then in DOS, used GRUB: rootnoverify (hd0,0) chainloader (hd0,0)/cylc boot to successfully boot Windows 2003. But when using the same method in Windows XP, it cannot boot XP successfully. What is the problem here?

Supplement: Sometimes in XP, there are prompts from ====== to >>>>>, but it cannot boot XP!

Using the geometry (hd0) command in GRUB, there are prompts like detecting the hard disk of XP: drive 0x80 (LBA): C/H/S=10012/255/63.sectoy countlsize=160842780/512 partition num:0, Filesystem type is ntfs, partition type 0x7 partition num:4, Filesystem type is ntfs, partition type 0x7 partition num:5, Filesystem type is ntfs, partition type 0x7 I wonder if there is a problem with the partition?

================================================= ===============
Under the condition of not modifying any files, using GRUB to boot XP in DOS has such a prompt: warning: Unrecognied partition table for drive 80. please rebuild it using a microsoft-compatible FDISK tool(err=1). current C/H/S=16383/16/63 starting cmain().......... Then the hard disk light keeps flashing red!

The content of menu.lst is rootnoverify (hd0,0) chainloader (hd0,0)+1 boot

================================================= ===============
Sometimes there will also be a prompt like A dsik read error occurred press CTRL + ALT + DEL to restart What a mess, I don't know the reason. The boot image is the same. Why is it normal in Windows 2003 but not in XP? Could it be that there is a problem with the hard disk partition of XP?

XP is installed on the first partition, and there is only one hard disk, no redundant storage. Please help all the experts analyze!

Oh~~ I have found the problem. Windows 2003 uses a 915 motherboard, while XP uses an NF-CK804 motherboard. Windows 2003 starts normally, and XP starts as the situation I described above. If the hard disk of Windows 2003 is hung on the NF-CK804 computer, it cannot start normally (Windows 2003 starts normally on the 915 motherboard), and if XP is hung on the 915 motherboard, it can start normally (XP cannot start normally on the NF-CK804 motherboard). It is the problem of the original motherboard. Please ask how to solve this problem for you. Or which version of GRUB has better compatibility!

Is it that GRUB has poor compatibility with NF motherboards or AMD CPU instructions?

The version you are using may be too old. Try the latest version from 2008-05-07: http://grub4dos.jot.com/

If it fails, quickly tap the Insert key at the moment of booting grub4dos, and post the debug information displayed on the screen.

Oh, but the old motherboard (915 motherboard) can boot normally, and the new motherboard (NF-NF4TS motherboard) cannot boot normally. I'll give it a try.

The problem recommended by the upstairs with GRUB has been successfully solved. There is another problem: why can't the [Options] BootKeys=0 in MSDOS.SYS lock the F5 key?

F4, F5, F8 are all ineffective

Then, is there any way to lock the F4, F5, F8 keys?
