Hi to all,new to linux and the forum.
I have an acer aspire 5315
Had Zorin 16.1, was always very very slow
Upgraded to 17 with usb download
All seemed to go well, all files checked, no errors
Shut down, restart and failed to boot
Message 'no bootable device found '
Will only boot from usb
manually set boot to harddrive, no joy
I researched forums but don't understand a lot about terminal.
All seems to point to BIOS fault
Have tried to repair grub2 in Gparted
Have tried Boot Repair, Bios info summary is at
http://sprunge.us/Db6n5D
It says to 'disable BIOS-compatibility/CMS/legacy mode', 'set BIOS to boot in EFI mode' but cannot find that ability in BIOS
Before the start up there is a grub bug error showing, although i think that has been there a long time as it has always been a bit slow.
Any pointers would be greatly appreciated
