Solved Windows won't let me access a partition

[Ace77]

So yeah. I installed Ubuntu Gnome on a new 20gb partition on my !!!SSD!!! and now Windows has decided to not let me access my mass storage partition on my !!!HDD!!! :sarc:

It looks like this in disk management:

And here's a picture of how disk management doesn't let me do anything to it except delete it

No, I did not transform the partition from nstf to ext or anything like that (ubuntu where the part. actually shows up it's nstf)

Any ideas? This might go to the linux side, I don't know.

Windows can not read Linux partitions.
But windows should be able to delete them.

So the options are greyed out, but I cant read the language. Which option is not greyed out?

If a partition is in use can windows delete it?

Like I said, delete is not grayed out (and help, but yeah) The thing is, I did not do anything to the mass storage when installing ubuntu, which is weird that ubuntu would just take it over. And, windows lets me delete everything except the boot partition C:

It does show as a NTFS partition, but maybe something is wrong with it, started on a wrong cylinder?
If you not using it, delete it and recreate it.

Not sure windows CAN do anything with a linux partition, no resize either. No reading, No writing. Only a delete function.

Remember Linux is the enemy of MS.

I use ubuntu, am typing on ubuntu PC right now.
You can use ubuntu to look at that partition.

IF your stuff is on it, boot ubuntu and you can run gparted to resize, change things, might see an eror message on it. etc....

Sorry for late reply, I had stuff irl. This is how the HDD partitions look like in GParted http://i.imgur.com/kPuFx7f.png And this is the missing HDD partition http://i.imgur.com/pAnN4MR.png I have no idea how to access it in Windows, is it because its not mounted or something?

Update, did a health check in gparted if its any useful

So after a bit of research, I find out the easiest way to change it to Windows partition is to format it. Which I can not do, since it has 800gb of data and I do not have a such external storage drive to transfer it to. So I need to transfer it to a Windows partition somehow without formatting it, like Ubuntu somehow did from Windows to Ubuntu when I installed it (for some reason). Any ideas are welcome! And no, I will not go on and download everything again with my horrible internet speeds

A few things
1) Bitlocker is on the HDD - that might be causing you some headaches.
I don't know enough about Bitlocker to advise you on how to correct a 'locked' partition.

2) You have two 100 MB partitons (one on the SSD, and one on the HDD). - both have the active flag set.
Try disconnection the HDD and booting - does it boot?
If it doesn't boot, reconnect the HDD and boot up.
If it does bot, shut down the machine and reconnect the HDD
Then launch an elevated Command Prompt (right click, run as administrator)
Type the following in Command Prompt:
Diskpart
lis dis
sel dis 1
lis vol
** screen shot if you need help
** you can exit Diskpart and Command Prompt if you're asking for help

sel vol 4
** should be the 100 MB volume on disk 1. If it isn't then select the correct 100 MB volume (not the one on disk 0)
inactive
exit
exit

restart the machine.

If you're not sure, post a screen shot after the lis vol command.

Alright. When I removed the hdd, my computer now boots up to Ubuntu by default instead of Windows ((even after plugging hdd back in, because bios set default to ssd now) I still could boot into Windows from Ubuntu boot screen) I also set the 100mb partition on hdd to inactive, but nothing happened? (except it's inactive now but yeah ) So what now?

I have no idea how, but I fixed it by giving the drive a new uuid and so Windows rescanned the drive or something like that /thread
