Hi! I have a very weird problem. My computaer was running fine, I wanted to install Ubuntu on it, so I created a bootable drive on a memory card which was in my phone. I did have Ubuntu on my PC before, it was intstalled from a bootable USB. I restarted my PC, opened BIOS and rearranged the boot sequence. I had one which said something like Linux Drive and one after that which said N/A. I have put both the Linux one and the N/A one before the HDD and CDROM, saved it and quit BIOS. Since then my PC is unable to even boot BIOS. I have tried to reset the CMOS about 10 times now, with jumper switch or removing the battery and still nothing, when I turn it on the fans start and then I have nothing, no beeps, just a no signal screen. What the hell should I do? I have never seen anything similar to this.
