[SOLVED] Installed Windows 10 on a new SSD and now I can't access my old HDD with Linux on it

So my situation is like this:
I have an old 2TB HDD with 2 partitions: one for Windows and programs, and the other for storage.
Last week Windows 10 crashed and I couldn't repair it.
I bought a new SSD and planned to create a dual-boot system.
While waiting for the SSD to arrive, I installed Ubuntu on my old HDD, on the partition on which Windows was installed. The other partition I left alone. Everything went well, my storage partition was safe and sound.
The SSD arrived and I installed Windows 10 on it.

The problem is now I can't access the old HDD. I see its partitions in Disk Management, but I don't know how to proceed so I don't format anything. If I simply assign a letter to that partition, will it work or will it break?

And now I can't boot in Ubuntu, although in BIOS the old HDD is the primary option. The SSD doesn't even appear in the EZ mode of the UEFI BIOS and it still boots from it.
At this point I am in the position of reinstalling both OSs, but I do not want to lose the storage partition.

I guess you know that Windows and Linux use different disk management systems. This means that you really really need expert guidance when attempting to make them coexist. Believe me, this is the voice of experince! Your best bet is probably the Ubuntu forum here:

Thank you for your reply. I know now more than ever that they use different disk management system, but I overlooked this aspect when I was installing linux. I'll head over to Linux Forums and see what I can gather from there. Cheers!

May be it's time to backup you DATA and convert that hard disk in to ext4 or something... ext4 will perfectly work with Linux
