I have spent a long time learning EZboot, GRUB, BCDW and other boot CD managers. I think GRUB has the best development prospects, with very powerful functions. The mutual adjustment between them can basically be used. Most of the guides for IMG, ISO and so on are successful, just some relatively special ones are not successful!

Now I am making a CD, which has integrated all the IMG and ISO files I need. The only thing left is that I haven't figured out the boot files for the system recovery of various brand computers. In fact, my purpose is: I want to use GRUB to guide the recovery boot files of the hidden disks of various brand computers to restore the system, because sometimes some brand computers need to be turned on in BIOS, or the MBR has been changed and does not support keys such as F11 to restore the system. But I don't know which file GRUB should call. I don't know if the masters can provide possible information about the boot files of various brand computers!?

Thank you!

This is quite difficult. The main thing is that the boot methods for one-click recovery based on HPA are not uniform.

If it's just the usual hidden partition form, you just need to remove the hidden attribute of this partition and add the active attribute, then directly load the boot sector of the corresponding partition. Suppose this partition is (hd0,6):

rootnoverify (hd0,6)
unhide
makeactive
chainloader +1
boot

Thanks for the reply from the upstairs. Well, this is also a way, but what I mean is, can we use this?

find --set-root /XXXX

chainloader /XXXX

boot

Is it like this? Just like booting XP, directly find --set-root /ntldr and then load this ntldr to start like that... Recovery should also call a file like ntldr to start, right? If so, will it work?
