Solved Windows 7 won't boot after installing dual boot Android-x86 via GRUB

[Deleted690]

I have a problem after installing Dual boot Android-x86 4.4 on my old netbook called ADVENT 9112.
After my old netbook booted, then GRUB loads then i choose Windows 7 and Windows 7 starts booting but Startup Repair appears, after half hour, the Startup Repair failed. Android-x86 works fine without problems.
So, what's the issue about dual-boot between Windows 7 and Android-x86

Did you create a restore point, or system image? If you did you can try a restore point, or re-image your drive. I never try any major changes, dual boot is major change, to my system without a full system image. Don't try the recommendation in the hyperlink without a backup. First time I tried dual boot, I made a mistake and computer wouldn't boot.
You can try installing grub on the partition that your Android is on. Windows doesn't seem to like Grub boot-loader replacement.
Same as recommended in this video, but instead of Linux, you install Android. This is how I have my dual boot on my laptop (Win7 & Linux).

i didn't backed up data on my old netbook, but it is there any linux distro that can read NTFS partitions?

Yes,
Does your Netbook have system restore? I believe it should.
Any Linux distro can read NTFS, you can also create a Windows PE disk, either will, Windows cannot read Linux partition, you have to install 3rd party software to do so.
Are you familiar with Linux or Win PE?
Here's an ISO SIW2 created and posted on SevenFourms for download. You can burn it to DVD with Rufus or USB with ImgBurn.

I get it, but it is ok to reinstall windows 7 on same win7 partition? Will GRUB won't be destoryed after reinstallling windows7? (sorry for my bad english)

English is not a problem.
Yes, GRUB boot-loader will be replaced with Windows boot manager, you can then use Linux live DVD or USB to install grub on the partition you have Android. You can use EasyBCD to set up Win boot-loader to point to grub boot-loader.

Make a complete system image/backup to an external drive before you attempt any of this! If you make a mistake, you can re-image your drive and try again.
