Laptop freezes during install of Ubuntu 15.10 from usb

Question

I'm trying to install 64bit Ubuntu 15.10 from a usb on this laptop:

ACER Aspire One Cloudbook 14" (A01-431-C2Q8) Intel® Celeron™ Processor N3050 (integrated Intel graphics with shared memory) Memory: 2 GB Storage: 32 GB eMMC

I get the Ubuntu loader and then it freezes.

I previously installed Ubuntu 14.04.4 LTS with no problems.

Thanks for any suggestions. This is my first venture into Linux.

Update: I switched to UEFI in the BIOS and installed Ubuntu 15.10 without issue, but then could not boot ('no bootable drive'). So I have switched back to legacy BIOS and am back with the issue of freezing during installation.

Update 2: Got through installation by using nomodeset in the menu options. But upon reboot the purple desktop just appears to flash repeatedly, and I can get no further.

Answer 1

The boot flags you need to boot are

edd=off noapic modprobe.blacklist=pinctrl_cherryview

APIC on that laptop likes to throw a fit when booting, and Ubuntu uses the Cherryview graphics for the chipset, which doesn't work either.
