It's been a while since I've done this, but I thought the hotkey was ESC |
| 32 |
not shift? |
| 33 |
|
| 34 |
All I had to do was use: |
| 35 |
|
| 36 |
GRUB_TIMEOUT=0 |
| 37 |
GRUB_HIDDEN_TIMEOUT=5 |
| 38 |
|
| 39 |
Grub will wait for the escape key to be pressed for 5 seconds, if no |
| 40 |
keypress, it would boot. |
