Windows 10: By installing Win10 Access denied to a partition

Hello,
I'm usualy using Win7 installed on a SSD (win7) and and a HDD for data.
I start installing Win 10 on a new SSD (disconnect SSD win7 and connect instead). Win10 installed and work like a charm except access through Win Explorer to G: partition of the HDD. I've access denied (see image bellow).. When I get access through command prompt (see image bellow).

Moreover, when I reconnect the SSD (Win7) and restart with, I've access to that G: partition *Rolleyes*Confused

I'll appreciate any help

Question about Win10 and partitions.



So I have a partition ready for Win10 but my question is will I still be able to access my other partitions once Win10 is installed? I keep hearing about the "recovery partition won't be able to be used" and I'm wondering if Win10 just doesn't play nice or if I'm good to go.

 

Admin10 and User10 'Access denied' after withdrawing Win7 user rights


Hi guys, recently installed Windows 10 Pro 1809 on a second internal drive.
All was well until I made a stupid mistake in Windows 7 that effects rights in Windows 10. *Banghead

PC:
Win7 Pro SP1 x64 [Legacy] on 1st drive, two accounts: Admin7 and User7.
Win10 Pro x64 [UEFI] on 2nd drive, two accounts: Admin10 and User10.

What happened:
After I installed Win10 on the second drive, I was surprised and annoyed to see that User7 was not only able to access the Win10 partition in Explorer (after reboot and log on ), but also to change and delete things on that partition. So I denied User7 all access rights for the Win10 partition.
Since then I not only get application startup errors in Win10, but both Admin10 and User10 are getting "Access denied" when trying to view the C: Win10 partition!
I tried to undo the steps in Win7, but can't change the Win10 partition rights anymore. (Access denied)
Ran sfc /scannow, which repaired things. Not sure what; CBS.log attached. That didn't solve the problem either.

My bad of course. I shouldn't have dabbled with things I don't really know enough about.... *Confused

So all help and suggestions are very welcome!

 

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that
