Re: What does it run?
However my ubuntu laptop was ubuntu because I tried windows 10 and was officially told windows 10 once installed can't dual boot because of UEFI (I was asking for the ubuntu install disk) So probably because of Dell not windows
Perhaps Dell didn't something nasty to impose that limitation. I bought a refurb HP Pavilion 500-314 that came with Windows 8 pre-installed, which I then upgraded to 10. This is a UEFI system. I then installed Ubuntu in its own partitions. Without any work from me, Ubuntu made itself the bootloader, and added Windows as a boot option.
I wouldn't be shocked if Dell tried to prevent that, but you probably would have been successful if you tried.
