I recently upgraded free from W7 to W10. (desktop PC).
Everything went well but I now suddenly have a blue screen entitled Recovery PC/Device needs repair error code 0xc0000001.
The suggested Enter/F8 solution does not work. I have no W10 recovery disc etc. but should have the original W7 installation disc.
Most of the on-line solutions require recovery hardware so is there anything I can try?
Presumably I will lose everything stored on the PC.
