I can't save anything, I've desoldered the CMOS battery and it won't reset, I can't reset to defaults, nothing saves. USB booting doesn't work, presumably because Secure Boot is on and the option to clear it is grayed out (and the BIOS won't save anyways)

What happened? When I go in the boot menu, there's always Ubuntu as 1st choice and it's pretty annoying. I removed the HDD but the entry still stays there, and I've never encountered something like this before.

The laptop is an Acer Aspire E1-510, and the BIOS worked fine before I tried Ubuntu on it.

On my Acer, Even though I removed Ubuntu over a year ago, it still showed two instances. I don't remember the details now, but when I was on the menu, there were options to delete the OSes in the BIOS. I deleted the two Ubuntu installations. I don't remember if I deleted Windows or not. I was thinking about it to see what would happen.

So, go into your BIOS and check for the options where you found Ubuntu. (mine was spelled in lower case "ubuntu") See if you can delete them.
