So I have this lenovo ideacentre B540 All-in-one that originally came with Windows 7. The customer bought it at best buy and it came with a free upgrade to Windows 8 when it came out. So the customer was using it with Windows 8 until he got some FBI porn virus on there. I was hired to reload windows 8 and have it dual boot with ubuntu. I put the windows 8 disc in, format the 1TB drive and leave about 200GB for ubuntu. windows 8 is setup and done.
i can no longer get this thing to do anything other than boot windows 8. cant get into BIOS, cant get a boot menu, can't boot from CD/DVD or USB through the windows 8 restart menu thing. what an abomination. any help?
