windows 8 stuck in endless preparing automatic repair

Hi 

I recently bought a sony vaio laptop with windows 8 out of the box.

Now the system is not starting

it says preparing automatic repair for some time then a blank screen comes up for  while and then a screen comes up saying repair not completed...it automatically restarts and same thing continues in a loop

please help with this

Interestingly, I had this issue with a PC recently. The problem was with an external device. Under the boot order the "Floppy Group Boot Priority" had "WD SES Device" listed. This told me something by "Western Digital" was plugged into the machine. Sure enough, there was a backup external hard drive plugged into the machine. Why this was listed under the Floppy Group Boot Priority I'm not sure.

I also noticed that under the HDD group priority was listed "WD My Passport". It's trying to boot from an external hard drive that has no Windows installed. I set this to the internal HDD and then unplugged the external drive. Rebooting got past that error.

Try this when power is off repeatedly press ESC. Key and turn power on u should be able to find system restore

I had the same problem too,

but after trying your method; my laptop worked straight away!

Many thanks!
