Does not detect OS

Post by Patrick_G »

Hi, I have been using Linux Mint 19.3 on an old Laptop. I like it so now I tried to install Linux Mint 20 along side Windows 10 on my 2017 Dell i7 laptop.
When I boot to the USB flash drive I choose from Legacy Boot: USB Storage Device.
Linux Mint 20 boots and I can log into my FIOS wireless connection and use Firefox.
When I tried to install Mint 20, I got a message: This computer currently has no detected operating system. So I Quit the installation.
I tried to boot again and look at my options:
I see at the boot menu for UEFI Boot there is a choice for:
1. Windows Boot Manager
2. UEFI: USB, Partition 1
3. Other Options:
Should I try booting to: UEFI: USB, Partition 1
I am asking because I don't know about UEFI.

Yes choose the UEFI USB option. Windows is installed in EFI mode which is why your system has the Windows Boot Manager listed.

Starting the stick in the UEFI mode will allow the installer to detect your Windows too.

UEFI is sort of a BIOS 2.0. For a quick overview, see https://www.howtogeek.com/56958/.
Might as well learn about it. Gonna be with us for a while.

Only if you're dual booting with Windows. Otherwise, i'd turn it off and stick with legacy mode.
