Thanks to all who have responded to this email. The information sent |
| 51 |
have solved my problems with the sata drives. I am very happy. |
| 52 |
|
| 53 |
For the record, I have used the above solution and it is working great. |
| 54 |
|
| 55 |
I hope one day grub will allow "root=UUID=something" then the problem is |
| 56 |
completely solved. |
| 57 |
|
| 58 |
I am very happy. Thank you all very much for helping. |
