Windows 7: CHKDSK Occuring in Win 7 boot for Dual Boot win7/win10 computer

CHKDSK Occuring in Win 7 boot for Dual Boot win7/win10 computer

Hello everyone, I have a Dell Optiplex 760 SFF that has both win 7 and win 10 installed on a 1TB hard drive in the following partition order:
500 mb system reserve, 100gb win 7, 750gb data, 80gb win 10
I've also disabled the metro bootloader, as it wastes times when booting to win 7.

Whenever I reboot to Win 7 after booting into Win 10 before, the system requires a chkdsk of the Win 10 and data partition. I looked around the forums here and the win 10 forums, and have disabled fast boot in Win 10 as mentioned throughout, but it still results in chkdsk being required.

I've tried to do this on other computers such as an MSI laptops with Win7, with similar results.

Is there something else I need to do so that Win 7 doesn't do disk check?

Thanks for all the help in advance.

Triple Boot - Win 7 x64 Ultimate x2 + WinXP-mce x1
 
 

Hello,
From what I understand of your post, I guess now one can have multiple UEFI partitions to choose from...
Not sure about win 10 since I've stayed away from it, but I have a UEFI Win 7, MBR Win 7, and MBR Win XP triple boot system. From all I read 2 years ago, it was impossible to have a dual boot stup with multiple UEFI systems. That might have changed. The only way I got to do it was by letting the "uefi Bios" default to UEFI Win 7, and by forcing a F-11 boot to another disk with a EasyBCD bootloader for my Win7 MBR / Win XP MBR partitions.
If your UEFI partitions for Win 7 / Win 10 are conflicting, maybe they report a chkdsk automatically since you disabled the Metro loader.
Thanks for your post as it informed me of something I thought was impossible. Sorry for not being more helpful.
Regards,
JohnPC

I don't believe that my hard drive is set for UEFI. I installed win 7 first before adding win 10 to the hard drive. and my hard drive properties state that the partition style is MBR. Looks like not many people know of similar situations and potential solutions to my problem though.

This occurs when you have Fast Startup (the default) set in Windows 10.
Fast startup is a hibernate like mode in Windows 10 and it leaves the drives in a state that Windows 7 does not understand, therefore it initiates chkdsk.
Turning off fast startup in Windows 10 will fix the problem.

Hi,
Yep Fast start is a bugger :)
I'd personally use cmd and disable hibernation as well inside win-10
Win-10 has a nasty habit of resetting fast start after major updates install
powercfg -h off

You can also for good measure disable fast or quick start up in your bios.

I did mention I disabled fast boot/startup.....re checking power options again shows that it is turned off. There shouldn't be any problems with the settings being reset since I installed win 10 to the partition last Monday, got it fully updated and ticked off fast startup.

oh.. look like fast boot and fast startup are two different things.. at any rate. fast startup is disabled. and fast boot won't exist for a bios only computer like the optiplex 760

wasn't uefi started to be used in computers that shipped with win 8? Or am I just being an idiot? From my limited knowledge I thought uefi was used as a replacement for bios and started being introduced to pcs along with win 8. Since this optiplex 760 started as a vista computer I thought no UEFI is included. If I'm wrong due to my lack of knowledge please excuse me.
I really just want to now how to dual boot win 7 and win 10, without a chkdsk occuring everytime I switch to win 7. I've tried out disabled hibernate completely as suggested, but didn't work. And like I said above, fast startup has been disabled since fully updating win 10.

Hi,
If you disable hibernation in win-10 using cmd as admin you should be okay
Then fast start will not even be listed in power options :)
