New SSD - recovery usb loop

Hi guys,

I bought a Dell XPS 8500 for my son as a starter PC, it came with no hard drive,

I installed a crucial SSD - this is recognised in BIOS and no faults found.

I have no  DVD so installed recovery media on USB following dells instructions.

When i boot from this in either legacy or UEFI it goes to the recovery & restore.

the smart repair can find master boot disck but no drives??

then I've been going in circles for the last 3 hours!!!

I either get 'media test failure' or if i select other boot mode i get no bootable drive found.

please help!!!
