I had Windows 8 and Linux Mint 15 dual booted on my laptop. When I first installed Linux, I wasn't able to load into because the grub would not show. To fix this, I used boot-repair from a Live CD. This time, I updated to Windows 8.1 and it showed a watermark telling me my secure boot wasn't configured properly. I then went and enabled secure boot (BIOS) and I believe it was after that that the Grub would not show once again. I tried to boot from a Linux CD again but when I try, it gives me the following errors:

error: failure reading sector 0x0 from 'hd1'
error: you need to load the kernel first.

Press any key to continue...

Before, it was giving me an error with sector 0x6d200 or something instead of 0x0. I am completely unsure of what to do. I do not know what other details to give except that this my have happened after I enabled secure boot, and I actually clicked reset to default setting so I am unsure if any other settings were changed in the BIOS menu.

hi1 suggests your hard drive. have you checked the boot order in the bios? –  bryan Oct 22 '13 at 3:32
EFI Boot? You may have to reinstall grub. –  Grizly Oct 22 '13 at 3:37
@bryan Legacy boot order shows: Notebook Hard Drive, Internet CD Drive, USB Diskette on Key/USB Hard Disk, USB CD ROM Drive, ! Network Adapter in that order –  Vee Oct 22 '13 at 3:40
@Grizly That's what I tried to do but I can't even boot into the Live CD –  Vee Oct 22 '13 at 3:40
You'd need to change the boot order to get to the liveCD (based on that list), I googled that first error, and it seems common to every distro! Can you turn off UEFI for the DVD drive? This might help (once its fixed: help.ubuntu.com/community/UEFI#Converting_Ubuntu_into_EFI_mode) –  Grizly Oct 22 '13 at 3:53

Turn off Secure Boot.

Linux Mint doesn't support it yet.

I turned it off, the Live CD would give me the same error. –  Vee Oct 22 '13 at 15:00
You commented above: "I changed it into legacy mode. This allowed me to run the live linux mint cd and reinstall grub using boot-repair" Is this ambiguous? I don't understand the problem then. –  Grizly Oct 23 '13 at 22:51
