[AcidHead]

Hi Everyone i'm new in the forums and need some help with a problem i have, so i
recently bought a new ideapad z710 DOS only laptop and installed windows 7 on it
everything worked fine than i dual booted openSUSE on the same HD everything still
worked fine but one day when i turn on my PC out of nowhere Windows could not boot,
and gave me an error with status code "0xc0000225" and error message "the boot
selection failed because a required device is inaccessible", i can't boot to safe
mode (the error happens to early in the boot process) and i can't use a recovery DVD
cause for some reason when i put a DVD in the drive and try to boot from it the PC
just Hangs on the MB's boot screen forever(That didn't happen before).

p.s. i have technical know how so feel free to speak geeky.

Thanks in advance...

"0xc0000225" and error message "the boot selection failed because a required device is inaccessible"
No other message? No extra information listed?

Linux still boots succesfully?

Are you using GRUB as bootmanager and is win7 just a boot entry?
Or are you using the win7 bootmanager and select linux there?

Can you boot to "Advanced Boot Options" by using F8? Select "Repair your computer". Does that work?

 

[AcidHead]

Well it also says to boot from a recovery DVD and chose "Repair your Computer" but that doesent work cause my PC just hangs at the motherboards boot screen if i try to boot from a live DVD, Linux boots normaly, i'm using GRUB 2 and i can't boot to advanced options cause the error occurs to early in the boot process...

The win7 bootmanager (launched if selecting windows in linux bootmenu) gives you error 0xc0000225! Can you please try http://www.sevenforums.com/tutorials/666-advanced-boot-options.html . "safe mode" is listed there? "repair your computer"? Has that F8 advanced boot worked before with linux in dual boot?

Can you see the win7 partition in linux and its files?

 

[Kaktussoft]

You know how to and can boot from a bootable DVD? Or none of the bootable DVD's work?

 

[AcidHead]

i can see and access my windows partition from Linux, and i can't access safe mode cause the error occurs imediatly as i chose to boot Windows, i know how and have bootable DVD's but for some reason when i try to boot from them the pc just hangs in the boot screen(that doesent happen with the same DVD's on other PC i own and dident happened on that pc before the error), i'm gonna try a live Pen Drive with "Make PE3" and see what happens...

 

[AcidHead]

i tryed setting boot mode to UEFI but than it only allowed network boot no hard drive boot no live media boot nothing so i changed it back to legacy support...

You need to have a bootable DVD or USB stick a so called "win7 system repair disc" or just a win7 install iso. So none of them boot? Even a linux live cd doesn't boot? Is dvd drive still working... check in linux if you see the files.

F8 advanced boot should work. It is a problem with win7 bootmgr, its bootmenu, or a the win7 bootstrap file it is calling. All of them can be checked and rewritten in win7 recovery environment.

DVD drive is working under Linux but booting from it any of the about 20 live DVD's i have doesn't nighter does safe mode(i'm repeatedly pressing F8 before i start my Pc until the error occurs still nothing), i'm going to try a live USB.

Can i install Windows on a partition from inside Linux?

 

[AcidHead]

At that point i don't care about saving my data i just wan't to reinstall Windows...

An expert can add an grub2 entry to chainload from dvd.

Can you boot from live usb?

 

[AcidHead]

Could just reinstalling GRUB work?

And maybe the reason i can't boot DVD's is my BIOS settings, i don't remember exactly what i had changed when i first installed windows and linux...

BIOS Settings Under Boot:

Boot Mode: Legacy Support
Boot Priority: Legacy First
USB Boot: Enabled
PXE Boot To LAN: Enabled

but Windows and DVD boot used to work with the same settings...

also i'm not sure how to make a bootable windows USB i ones made one with Unetbooting by changing the USB's file system to NTFS just before Unetbootin started writing to it, but i don't remember the results...

It's not a grub error!!
To burn a win7 install ISO : Windows USB/DVD Download Tool - Microsoft Store

Or just copy all files form installation DVD to root folder of usb stick. It must be a primary partition and marked ACTIVE.

Did it boot succesfully form usb stick? Were you able to run "Startup Repair"? If so... linux isn't bootable anymore I assume.

When running "Startup Repair" you saw a screen where you can click "view diagnostics detail results" or something alike. Click on it. What tests didn't give a status 0x0, and what was its status?

 

[AcidHead]

The USB booted successfully but Start up Repair was unable to solve the problem, should i use some command from the command prompt to rebuild MBR or some thing??

After running "Startup Repair" click on "view diagnostic and repair details". What tests didn't end with status 0x0? And what was its status?

If you boot from the usb and select repair computer computer it's scanning the disk to find windows. Which drive letter has windows? For example drive D in this example.
