Windows 7: oxc000000e Boot failed-required device is inaccessible (Windows 7)

booting to lenovo-part gave you a CMD screen only you told me... so that doesn't work at all. Also the one key recovery on boot doesn't work. That's because you rebuild the MBR by performing "startup repair" or write MBR by partition wizard. The special scan key for boot to recove to factory settings was built in a customized MBR!

So you can't restore to factory settings anyway.

What's solution? how i can use factory settings?

Since Windows 7 is totally corrupted an you saved all important files already. Did you?

boot from partition wizard dvd. 420GB is primary and active. If not make it primary and active.
Now format that partition as NTFS and "default cluster size"

Your Windows 7 now is completely empty now. Post screenshot afterwards

Do you have Windows 7 64bits installation dvd already? Valid Windows 7 licence (is on COA sticker on back of laptop)?

Why do you want factory settings?? Do you want all the bloatware ?
You can install Windows 7 on laptop yourself no factory settings needed.

As told you before OnKeyRecovery isn't working now!! so it won't work after reinstalling as well.

To be very save:

1. delete to 200MB system reserved partition. It isn't needed and can be recreated
2. shrink 420GB by about 70GB , so 70GB unallocated space appears
3. create a primary partition in the 70GB unallocated space
4. format that partition as NTFS (default cluster size)
5. mark that partition as active

Now you can install Windows 7 there. Very safe!! All stuff will still be an other partitions!!!
And you can also do everything what you do now. But ... nothing works now ;-(

new disk partioning and one key recover feature - Lenovo Community tells you it's a piece of crap!!

do you think have way for load windows 7 again? i really don't want lose my application in lenovo!

So lenovo say if resize partition C. OKR doesn't work. is that right? if drive c have 50gb i don't save my files in drive c and have to recovery it with GetDataBack

What applications?? none of them are working now anyway!! Nothing will be lost if reinstalling in 70GB partition I told you to create

I don't have OKR but I know it's very unflexible peace of crap.

What applications are you afraid to loose? What do you mean by genius all the time?
