Can GRUB have a hotkey to enter at boot? Like one-key restore where pressing F11 can enter the restore state? Does anyone know?

That's great. Look at the help file.

Is this the help file you wrote? Or some other help file? Why can't I find it?

There are official instructions, and I have my beginner's tutorials.
Follow the official instructions.

Which item in the description is it talking about? I'm stupid, please point it out for me?

Oh! I see, but I still want to ask whether bootlace --force-backup-mbr --boot-prevmbr-first --time-out=3 --hot-key=0x3920 --mbr-disable-floppy 0x80 needs to be in the same directory as the GRLDR file? Also, can the GRLDR file I renamed to XYldr be used with this command?

If you are reading my beginner's tutorial, it is recommended to look at the latest version from 08-27, which has the usage of renaming files. Of course, these instructions are all in the official documentation. Read it several times and you will understand.

I just noticed that the directory you provided is already the latest version.

For example, I want to press F7 within 3 seconds when booting to enter Grub4dos, and if I don't press within 3 seconds, enter XP. What is the command?

What I don't understand is why when I use the shortcut key to boot GRUB through the MBR, the main system can recognize grldr but can't recognize the renamed xyldr file. However, when booting with NT, it can recognize my xyldr file.

After default installation, download DSPTW.EXE. Run the following code to complete the key modification. This code is for the 20071111 version.
ECHO Writing 00h...
dsptw 0 0 0 /m /hex:EB5E01030041 /Y
After completion, press F7 to enter within 3 seconds.

Use the attached grubinst.exe I provided to deploy.

grubinst.exe --mbr-disable-floppy --boot-prevmbr-first --boot-file=xyldr --time-out=3 --hot-key=F7 "--key-name=<F7>" (hd0)

A great expert.

Grubinst.exe also needs to be modified accordingly. Of course, if you use other installation methods, you have to figure out how to modify it yourself.

If the hotkey has already been installed, how to remove it?
