As the title says. Please, everyone, give some suggestions

Using GRUB.EXE to invoke NTLOAD from a floppy disk to load the WINNT system

I am going to enhance the grub's chainloader command so that it can directly boot the ntldr file. It should be done in the near future, please pay attention to downloading the files like grldr, grub.exe and grub4lin in the following FTP: ftp://ftp.linuxeden.com/tinybit/ for testing. Now don't test because it hasn't started yet. It should be ready after one week.

When making, please test whether the following module can be started___http://bbs.wuyou.com/cgi-bin/attachment.cgi?forum=33&topic=1387&postno=9&type=.rar&name=Idiopf_1108629898

Then what exactly is it? Is it an operating system? Or is it a boot file? Is there any description of its file structure?

It is an ISA module in the mainboard BIOS, only over 30KB.

I haven't studied this, so I don't know what to do.

I used to make one, which is executed by the Grub boot floppy image solution. The floppy disk is formatted under XP, and files like NTldr, boot.ini, Bootfont.bin, Ntdetect.com, etc., are copied in to make an NT boot disk.

I also want to know how to start the XP Recovery Console operation after booting DOS. Sometimes it is needed to use the commands inside when repairing computers

Refer to the floppy disk image I made before: http://wangsea.ys168.com, specifically newxp.ima under the disk.

I agree with your statement. I also want to know. There is also a small problem. I can enter the safe mode of XP but cannot enter the system. I don't know what the problem is. Also, can XP restore the registry in DOS?

Just made it. The GRUB chainloader command can start the recovery console. Assuming the recovery console's boot file is a 8192-byte bootsect.dat file, it can be like this:

chainloader --load-segment=0xd00 --load-offset=0 --boot-CS=0xd00 --boot-IP=0x256 (hd0,0)/bootsect.dat
rootnoverify (hd0)
boot

Still in the process of improvement, hoping to directly start the CMLDR file in the future.

Download grldr, grub.exe, grub4lin from ftp://ftp.linuxeden.com/tinybit/ to test. Note that this function is available in versions after March 1, 2005.

Don't test now because it hasn't started yet. It should be okay after one week.

Dude, is this function done? How to use it specifically? I'm concerned

NTLDR is not easy to boot directly. It heavily relies on the partition it is in, that is, it is bound to the partition. When NTLDR boots, it assumes that it is booted by the NT boot sector and records the information of that partition (it needs to find files like boot.ini from that partition). To boot it from outside the partition with GRUB, it still needs to go through the NT boot sector. This is the usual method:

chainloader (hd0,0)+1
rootnoverify (hd0)
boot

The above assumes that (hd0,0)+1 is the NT boot sector (similar to the DOS boot record, this is the NT boot record).

Bu Dian Brother: I remember you said before that you wanted to study the storage location of parameters in boot.ini. How is it now?
