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

[Kaktussoft]

And now the msahci.sys error stays?

No error 0xc000000e anymore.

You told me before... e:\Windows\system32\drivers\msahci.sys is simply not there!
Someone deleted it!

dir e:\Windows\system32\drivers

any files there?

You can try to boot and enter BIOS settings. Set SATA to IDE (sometimes called legacy) save settings and try to boot. Post results. If still problems, put setting back!

Confirm that you Rebuilt MBR after marking 200mb partition Active with PW CD: How to Rebuild MBR with partition magic? Partition Wizard Rebuild MBR Video Help.

Confirm you then ran Startup Repair three separate times. Not two times. Three times.

Then confirm you did all of the above with the Win7 partition itself marked Active.

Please describe it exactly?

How much more specific do you need:

From booted PW CD mark the 200 mb System Reserved boot partition Active by rightclicking to Modify>Set to Active, click OK.

Then click on Disk 1 to highlight it, from Disk tab select Rebuild MBR, OK, APply both steps.

If this fails to start Win7 boot into Win7 DVD System Recovery Options or System Repair Disk to run Startup Repair - Run 3 Separate Times until Win7 starts on its own.

If these steps fail, change the Active flag to Win7 partition itself and repeat the steps above exactly.

If these steps fail then we have to consider the possibility your original problem was infection and attempt to disinfect and then run the repairs again. Steps here: Troubleshooting Windows 7 Failure to Boot

Since you have 3 primary partition and 1 extended one, you already have the max of 4 partitions.

Within PW delete partition 200MB (partition is not really needed)
Make 420GB partition smaller. Make it 350GB or so. There will be 70GB unallocated space then. Format the unallocated space as NTFS (quick format) and make it primary. Mark that partition as active.

Now of course apply the changes. Post camshot when it has done the job.

important drivers needed later maybe

 

[Kaktussoft]

Or use Lenovo Drivers Update Utility - CNET Download.com to update all your drivers later

 

[moh3en]

Kaktussoft Drive C is now 420gb and Drive D is 30gb. i want change it. beacuse before all files was in Drive C and lost it.
Now i want 50gb for Drive C and factory setting and other in Drive D. if change partition Not a problem? for factory setting!

Also don't tell me about how do factory setting?

 

[Kaktussoft]

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?

 

[Kaktussoft]

Since win7 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"
How to Format Partition with partition magic? Partition Wizard Format Partition Video Help.

Your win7 now is completely empty now. Post screenshot afterwards

Do you have win7 64bits installation dvd already? Valid win7 licence (is on COA sticker on back of laptop)?

Why do you want factory settings?? Do you want all the bloatware ?
You can install win7 on laptop yourself no factory settings needed.

Also can i resize drive c to 70gb and other for Drive D.. is that problem for recovery mode?

[Kaktussoft]

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 win7 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 ;-(
