I have an Acer Aspire E5-573G with Windows 10 installed in UEFI mode and Linux Mint 17.1 installed in Legacy mode.
Recently I upgraded the BIOS to the latest version available in the Acer support page. After that, I can't boot to Linux Mint, GRUB shows up but Mint won't boot. Booting up in recovery mode, the process went stuck with the following error:
[0.158892] pci 0000:00:14.0: can't find IRQ for PCI INT A; probably buggy MP table
After that, the boot process freezes and the only thing showing is a blinking cursor. I really have no idea what happened here. I figured that maybe I can boot into a live USB and retrieve the data inside the Mint partition, and just reinstall it afterwards. But apparently even a live Linux Mint USB won't boot.
Can anyone please explain what is happening there, and if there's any way to fix this? If there's any material I should post just let me know. Thank you in advance! :)
