So your /dev/sda is being seen. Not sure why the UUID hasn't been read, but
you could do 'root=/dev/sdaX' where X is the correct root partition.

This would replace the 'UUID=59...'.

 

I just tried this. Because the /dev/sda9 is the root fs, so I used 'root=/dev/sda9' to replace the original one. But it also the same error as the following. Detailed is also attached.

Loading, please wait...

mount: mounting none on /dev failed: No such device

The fs in my pc.

root@gavinguan-desktop:~# df -h

/dev/sda9              31G   14G   16G  47% /
