Neither Windows 8 or BIOS wont boot after linux install.

[Dylan-periastron]

Hello,

I've recently been dual booting windows 8 and fedora 20 (and one point ubuntu). My fedora kernal wouldn't load in GRUB one day so I decided to reinstall fedora using a live usb (My laptop doesn't have a OD). unfortunately when I was freeing up space on my partition I may of deleted something I shouldn't of, because now when I boot up. boot manager only gives me the fedora grub boot option. I can't even access my BIOS or recovery mode. the only command that works on boot is f12 which brings me to a optionless boot manager.

I've been going through forums and forums to figure out what I may have done. but unfortunately I'm a bit new to linux so I'm unable to pin point exactly what I've done wrong. I've installed a windows 8 iso on a live usb and the boot manager (and Grub) won't pick it up. I'm at a loss. luckily my new fedora installation is working and I know my windows partition is still intact since I'm able to mount on it and take files I need.

here's my output for fdisks -l

Here a site that may help you out with your problem:

It appears that you may have overwritten your GRUB

Since Fedora still works... I would open a terminal in Fedora and update grub. sudo update-grub ..then I'd reboot and see if the Windows loader shows up on the grub menu. I haven't used Fedora so don't know if it uses the sudo command, but if it does this might work.

Unless you were in the BIOS you should not have been able to mess with it. You may want to check on flashing a new copy from your computer manufacturer.
If update-grub doesn't fix it install boot-repair or make a live boot-repair CD and use it to fix you up. It has the advantage of creating a report online you can point us to look at if it fails .

Double and triple check your access to BIOS. Nothing you have done to GRUB or either OS should be able to affect your firmware. You may be pressing the wrong access key or hitting it at the wrong time.

if I remember correctly it should be sudo yum update-grub
