Does your machine have USB boot support? If so, you can use one of the following methods.
1。First boot to DOS from the USB flash drive, then run GRUB.EXE under DOS. So you only need to make the USB flash drive into a DOS boot disk and copy the GRUB.EXE file onto it.
2。Copy the GRLDR file to the root directory of the USB flash drive, then execute the bootlace command on the USB flash drive. This can also install GRUB's boot code onto the USB flash drive. You can do it in two steps. First, create a bootable DOS system on the USB flash drive. After DOS starts, just run bootlace 0x80 or bootlace --floppy 0x00 under DOS. The former assumes your USB flash drive is the first hard disk under DOS, and the latter assumes the USB flash drive is the first floppy disk under DOS. After that, check whether there is a GRLDR file in the root directory of the USB flash drive. If there is, then it's done; if not, you can now copy GRLDR to its root directory, and then it's done too.
These two methods may not always succeed. If one fails, as we said before, it is caused by the machine's motherboard BIOS, and is very hard to solve.

Nope, my USB flash drive can't use your method：
1，GRUB.EXE hangs
2，Bootlace 0x80 reports that the partition table is incorrect
Explanation: my USB flash drive was made with USBOOT in HDD mode！
Possible reasons for failure：
1，BIOS
2，USBOOT
3，GRUB4DOS
1，GRUB.EXE hangs

Hehe, I'm afraid this may be serious. I suspect there's a problem with that partitioning tool of yours! Upload the first 63 sectors of the USB drive and I'll take a look.

I've also been working on GRUB booting from a USB flash drive these past few days, still learning.

GRUB is a good thing.

Many BIOSes do not support GRUB-booted USB flash drives. I've tested this many times. IBM BIOSes, Founder BIOSes, and ECS BIOSes, which means Lenovo's, all do not support GRUB-booted USB flash drives. Even booting into DOS from the USB flash drive and then loading GRUB.EXE doesn't work. All ASUS boards support GRUB booting, and TCL laptops also support GRUB booting. The BIOS seems to be AMI!
If the OP's BIOS doesn't support it, then just give up. It's not GRUB's fault, it's a BIOS problem!

So if that's the case, does that mean the motherboard doesn't support it?
