Ubuntu screen freezes in Acer

Question

My Acer Aspire's USB ports fried in the middle of a system recovery. So I pulled my internal HDD and placed it in an external HDD casing and installed Ubuntu on it as a bootable external HDD using a Dell Inspiron 15 inch.

Now I want to use this external HDD as the internal HDD on my Acer but this HDD works fine on the Dell (as external HDD) but freezes at boot-up on the Acer Aspire (as internal HDD). Since the USB ports are fried and it has no optical drive I have no way to boot the acer except this HDD.

I think its a problem with screen resolution but I shall be grateful for any possible answers.

Answer 1

Some Acer Aspire Ones has this problem. Presently, the Acer Aspire One 522/722 only boots Ubuntu 11.04 (or higher) if the BIOS option "Network Boot" is put on top of the list (positioned first) in the BIOS "Boot" section!

You can make that change in the BIOS by pressing the F2 key at Boot and setting the "Boot priority order" like: "Network Boot" > "USB-HDD" > "HDD0". Use the F5 and F6 keys to move items up and down in the menu. Failure to set NetBoot as the first device to boot may result in serious problems, like frozen login screens.

There are more information in this forum page. http://ubuntuforums.org/showthread.php?t=1811178. I have tried some of the other fixes mentioned there, but only the boot order change in the BIOS works for me.
