Having a lot of problems with a new Dell XPS 15 (L521X) which I finally got to boot after upgrading the RAM and it hanging on boot up.
Once I got that fixed I decided I wanted to create an extra partition for dropbox to sit on. I used EASEUS Partition Master to split the 750GB main HDD into a 350GB & 400GB partition. Something went wrong when performing the partition and the machine will no longer boot. Here's as much info as I can give:
When the machine powers up I get presented with a screen saying:
Recovery. Your PC needs to be repaired. A required device isn't connected or can't be accessed. Error code: 0xc0000225.I've tried to perform an automatic repair which doesn't work and thought that I'd just try and reinstall windows.
Press Enter to try again
Press F8 for Startup Settings
Press Esc for UEFI Firmware Settings
The problem is that when I go through the install options I cannot see any partitions or drives. If I go into DISKPART and list disks it only shows the USB drive I am booting from.
I just want to try and reformat the HDD and start a fresh install but I'm not exactly sure what the process is and the specific steps involved.
Any help trying to fix this would be much appreciated.
