Hi, O a 2 months old Surface 4 ( i5, 256gb ) - a simple restart ended with a Inaccessible_Boot_Device error. I've tried to restore, reset, erase - all end up in some sort of error. The farthest I've been was to create an active USB Flash drive, copied SurfacePro4_BMR_15_3.613.0 onto it and booted Surface 4 with it. After a while, it asks for Language then ends up with this error: "Unable to reset your pc. The system drive cannot be found" If I go into Troubleshooting, then Command Prompt it lists the drive as x:\> drive c: doesn't exist and if I list the directory of drive X, the entire Windows files and folders is there. Right now I'm traveling outside the US ( duh! that's why I've bought the surface in the first place - the lightness of this product ). I got no idea what to do, appreciate any advice or ideas!! Thanks in advance!
