@zme-ul AIO Boot uses a1ive grub2, hope you will try it

Sorry [grldr.mbr.txt](https://github.com/chenall/grub4dos/files/1009327/grldr.mbr.txt)

I skipped the partition table. 0x1B8-0x1FF will not be overwritten.

This problem does not occur frequently [grldr.mbr.txt](https://github.com/chenall/grub4dos/files/1009602/grldr.mbr.txt)

Sorry [mbr.bin.txt](https://github.com/chenall/grub4dos/files/1009628/mbr.bin.txt)

Thanks! Grub4Dos using CHS? But this information is returned by Windows. You can create a partition using DiskPart to test it. Grub4Dos is currently working well on this partition table....

This is what you need. [5mb.bin.txt](https://github.com/chenall/grub4dos/files/1067339/5mb.bin.txt)

I renamed it aiogrldr. This file is located in the root of the drive.

It's version 0.4.5c. I also encountered this error in this version.
