Dual Boot: Unable to access Windows NTFS Filesystem from Ubuntu 18.04
-
NTFS signature is missing.
Failed to mount '/dev/sda4': Invalid argument
The device '/dev/sda4' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around? -
Any reason you're duel booting instead of running one as a VM?

Installed Windows, shrank drive, installed Ubuntu 18.04.
Unable to mount the Windows drive even though shutdown is clean.
Windows is (or should be) sda4,..
sda1 - ntfs
sda2 - vfat /boot/efi
sda3 -
sda4 -
sda5 ext4I'm following this (which has worked in the past)

What happens when you mount sda1?

No 'real' reason I don't guess. I know with 8GB of memory, I should have plenty.. But I'd rather have all of it available to the OS - Esp Windows

sda is listed as the recovery partition,.. and likely doesn't have any of the User data.
That being said,.. I'll check that.

Might be a stupid question, but can you still boot into the Windows install?

Yes, both boot fine.
Ubuntu is faster and the default, but Windows boots

Could this be an issue with a newer release of NTFS? What Windows 10 version is it?
-
Is bitlocker or another encryption / security solution in play? I think bitlocker would have caused grief with the linux install in general, but I've never had the pleasure of messing around with it too much.
How about just booting a live linux? Can you see and automount the windows partition from a live disk?
Other possibility, is it ReFS instead of NTFS?

ExFAT- the partition is listed as NTFS in Ubuntu and Windows.
I’ve been able to read a exFat partition via USB.

I’ve not set up bitlocker, but it is listed in Disk management. And I have looked into this.

I had a weird problem once where Bitlocker turned itself on. Caused all kinds of problems with what i was trying to do (images)... killed it and life was good.

Can you try accessing that partition from a live ubuntu installer?

Follow up, yes I can mount and access /dev/sda1.
But there isn't anything there other than the recovery.

Interesting, that's so weird.
