I installed Ubuntu 13.04 as a replacement to my old 12.10 installation from a usb pendrive.
The install went perfectly fine.However,when I rebooted,my computer did not detect ubuntu and got stuck on the
please insert proper boot media screen.
I have used ubuntu exculsively from ubuntu 11.10,With all of them fresh installs.My most recent installation is Ubuntu 12.10 64-bit,and it worked perfectly.
I tried installing ubuntu 13.04 by overwriting 12.10,but then all of this happened.
It seems my computer cannot detect 13.04 at all,as my UEFI BIOS does not detect the os either.I have reinstalled ubuntu 13.04 two or three times to no avail.I have tried some other solutions like trying to reinstall grub
but then I am a noob and i probably messed it up.I Suspect the problem is either the UEFI or GRUB.I have ensured that grub is installed on my system however.
Please advise on how to make ubuntu boot again.I do not mind re partitioning the computer and whatnot as i have backed up all important data.I would also ask for the solution in idiot-proof terms,(like copy pasting commands).
If you need my hardware configuration,let me know,but i suspect this is a fault on ubuntu's end.
