[Help] Ask about the problem of grub4dos accessing the USB flash drive loaded by the USB driver under DOS
Introduction of the problem:
The unit has eliminated 2 old laptops (Dell Inspiron 8200), and the hard drives have been removed. And I don't want to configure a new hard drive in the short term, so I want to play without a disk. Originally, I wanted to use the optical drive to run PE, but found that the built-in optical drive it comes with cannot be recognized. Both 2 units have the same problem. I don't know if it is a problem of impedance matching after removing the hard drive. I want to boot with a USB flash drive, but found that USB boot is not supported. Fortunately, the floppy drive can still be used. The current idea is to first use the floppy drive to boot, load the USB driver under DOS, and then use grub4dos to boot the PE or image on the USB flash drive. After repeated checking of materials and experiments these two days, the current progress is as follows:
Now I can use the floppy disk to boot into DOS, and successfully load the USB driver with device in config, recognize the USB flash drive, the drive letter is D:, and can access it normally, but after running grub4dos, grub cannot recognize this disk. I have tried (hd0,0)~(hd1,5), no. I don't know how to use the find command very well, but it doesn't seem to work.
Now my judgment is: Is it that grub can only access physical drives, and in my case, after booting into DOS and loading the USB drive letter under DOS, grub cannot access it.
Is my judgment correct? What are the solutions?
