I'm trying to install Ubuntu alongside Windows 8 on my laptop. During the installation, I get to the bit where you select if you want to dual boot Windows and Ubuntu, or wipe the whole disc and just have Ubuntu there.

Rather than asking me whether I would like to install alongside Windows, it tells me that there are no operating systems detected, and the only option I have is to wipe the entire disc and continue.

I looked on the Internet, and it suggests putting the computer in Legacy boot, instead of UEFI. I tried this, and I get the dreaded Syslinux.... Peter Anvin et al error. Basically, the USB won't boot at all, not even to the Ubuntu splash screen. This was a frequent error on my little netbook, and it turned out to be the file system causing the problem. I don't think it supported FAT32 bootable drives...

It also says to try booting with Secure boot turned off, but the option is grayed out in the BIOS, so I can't.

Any ideas guys?

The laptop is an Acer V3-571G (Intel i7-3610QM, 8GB RAM, Nvidia GeForce GT 640M - 2GB VRAM).

Please help me!!
