I don't see why it won't work. You only need /boot for two things: |
21 |
|
22 |
- at boot time, the boot loader must be able to see it so it can load |
23 |
the kernel |
24 |
- when you update grub, you will overwrite files to /boot |
25 |
|
26 |
As for as the BIOS/EFI is concerned, a stick is like an hdd - just |
27 |
another drive, nothing special about it. If signing is involved, it's |
28 |
the boot image that gets signed. |

I say go for it and test it out. What have you go to lose? The thing |
31 |
will either boot off a stick or it won't, this test won't damage anything |
