I've got a Vaio laptop that used to work with 13.10. I did an upgrade to 14.04 and since then it does not want to boot any more, that is it doesn't seem to reach grub: I'm stuck on a "BIOS" screen telling me "Windows (sic) failed to load : recovery solution, contact vaio,..."
Running boot-repair does not help (http://paste.ubuntu.com/7309686/)
I wiped out my SSD and did a fresh install of 14.04 (default options) : nope. Also tried fresh install 13.10 : nope (even though boot-repair tells me "no error" this time)
I tried Fedora : success!! (but I'd prefer Ubuntu)
I tried 14.10 again but using a Legacy boot this time instead of UEFI : success but it takes 14s to boot compared to the previous 3s! That's not really satisfying!
- by "wipe out" I mean delete MBR and GPT informations by writing 0s on the disk (dd if=/dev/zero ...). Could it be an issue?
- any ways to know what's wrong during the boot process BEFORE grub is started?
- can it be related to a BIOS/EFI bug in the firmware?
- Any idea what could be the problem?
**Update : **
I checked where grub was installed but I couldn't find it (see this ) ?! I dumped the 512k at start of the disk and ... there are all 0s !? It should contain grub no?
