Windows 10 Installation issues

[Steve2926]

Boot using wimboot mode to Setup.
Then press SHIFT+F10 to get command console
Then use DISKPART and type these commands
DISKPART
LIST DISK
EXIT
do you see the USB drive and the hard disk you want to install to listed?

If so try these commands (booting in UEFI64 mode):
DISKPART
LIST DISK
SEL DISK N (where N is the number of the disk you want to install to)
CLEAN
CONVERT GPT
EXIT

Then try to install

If booting in MBR mode you need to use CONVERT MBR
