Solve the problem of garbled hard disk/U disk

First of all, let
me talk about the problem: when my hard disk installed Linux on the computer, due to an operation error, the system was loaded on the hard disk (it should be in the USB flash drive)
. If you encounter the same problem as me, you can try the following To get the method, a dead horse can be a living horse doctor.

Solution: (Be careful not to store anything in the hard disk after the garbled code)

1. Need an empty hard disk, make a USB boot disk (I use Master U)
2. Enter PE
3. Insert the hard drive
4. Open DiskGenius
5. Click on the hard drive you want to recover
6. Rebuild Master Boot Record (MBR)
7. Click on Tools in the menu bar
8. Search for lost partitions
9. You will be asked whether to ignore or keep it. If it meets FAT32, it will ignore it, and NTFS will keep it, then save and restart.
