Windows 10: How do i reinstall Windows on my laptop without loosing any data? I cannot boot into the...

Hello,


I made a huge mistake of editing my msconfig and changing the maximum memory and now I cant boot up my laptop. So the best option i know is to reinstall windows.



So... how do i reinstall Windows on my laptop without loosing any data? I cannot boot into the laptop, so i cannot do a backup

:)

 

AMD data change.......no boot up problem

1st: go to bios, check boot device TYPE priority (cdrom/hdd/etc.)
then, go to hard disk drives (still under boot category), and check if your system hard drive is at 1st place (IF you have more than 1 hdd)
2nd: if your bios boot settings are OK, run windows 7 installation disc, go to repair your system, run fixmbr and fixboot options (i think they are at same option on windows 7 repair - startup repair or something like that)
3rd: if your windows 7 installation disc cannot find your windows 7 installation, reinstall it, but take care - you may have bad sectors on your hdd

please, go step by step, and dont read 3rd step warning before you try 1st and 2nd xD

you can also disable "LAN boot ROM" option under "integrated devices" bios category to never see that meesage again (at least 3 NVIDIA Boot Agent lines xD )

 

Windows 10 won't boot, repair, recover or reinstall

Thank you, Gerard! I appreciate your help.

I tried using Win 10 boot media to reinstall from scratch. Install chugs away for a while then shows me a list of partitions on my hard drive. No matter which I select, Windows can't be installed because they're GPT partitions.

I've also tried running chkdsk /r /x as suggested in another post. That seemed to run without any problems, but when I restarted I eventually got a blue screen with error 0xC0000021a.

At this point it's looking like I need to completely reformat the disk and reinstall Windows from the boot media. Is that the next step? I've recovered my data - which is all still accessible.
