I have decent experience working with Ubuntu and windows together. I recently decided to try a new flavor of Linux and uninstalled Ubuntu. I hated it and reformatted the partition. To easily uninstall Ubuntu (if I ever needed to) I used wubi to install it. I walked away from the computer as it was doing its thing, I came back and it was shutdown. Normal for power conservative windows 8. After trying to boot today, I got a
error: unknown filesystem.
I looked up how to solve the problem, I tried looking for my (hopefully) installed Ubuntu partition and couldn't find anything. I tinkered for a while and found little success. So, being kinda tired of the dual boot and windows, I decided to wipe everything and install Ubuntu and figured it would fix grub. I restarted my computer (Lenovo G560) and the bios screen didn't offer any boot options like it had yesterday. I tried every key combination and pattern I could find on the web. Still got the grub error page. I tried just plugging various bootable USBs and CDs that worked before when I had access to the boot menu. No luck. I pulled my hard drive out and used an adapter to plug it into another windows computer and used EasyBCD to fix the MBR, no luck there.
My question is how to either access the BIOS boot menu, fix grub, or wipe and install Ubuntu via my other computer onto the hdd.
