Been using Ubuntu for years so know my way about Linux fairly well. Tried the Live KDesktop spin and very impressed. Decided to install to a USB before I fiddle with my main system hard drive partitions.
Installation went fine, no errors except whenever I tell the bios to boot to the named USB disk it goes to GRUB on my mains system. Tried it three times thinking I may have missed something but same result.
Viewing the drive on gparted it shows the main partition as lvm2pv - was expecting it to be Ext4 so am a wee bit baffled.
It is nothing to do with safe boot as I have that disabled.
Any pointers appreciated.
