Question Windows 10 won't boot after i unplug my second HDD that contain windows 7

[PytGamer]

Hi, i am really confused here, i am quite okay when it comes to computing but this i really never faced before, and i have looked for it all over the web but seems to no one have a clue, so to start i have 2 HDD one is 1TB WD Green and it's the one that i have installed the W10 on it and the other one is 250GB WD Bleu and it contain the W7 on it since 2012/2013, so the story is that i am hearing a weird noise from time to time coming out of my HDD (this is the sound you can hear at second 4 and 7

View: https://youtu.be/RQ7SjlMjIQg
should i be worried?) i don't know which one is it but it's probably the Bleu WD so since the current situation that we're living on (Covid-19) here where i am staying it's not possible to find a store that sell a Hard Drive (Probable one), that is why i am really worried about my data, and i decided to copy my important files to the Bleu WD HDD, unplug it and leave it till i find a chance to buy a new one, move my stuff and make a backup, but when i did that and started the Machine i got a message at the start after the bip "there's no operation system on your HDD press ctrl alt suppr to restart" something like this msg, i was surprised so i thought is my W10 installed on my other 250GB WD Bleu when i am pretty sure that it's on WD Green so i have unplug the 1TB Green one and plugged back the Bleu WD and since to get access to Windows 7 my system have to pass to windows 10 then choose which one to boot to, but i got a blue sky screen Recovery (Your PC/Device needs to be repaired) i hope if there's anyone here can tell me how to fix this problem since i don't know how this is really get mixed between the two HDD thanks in advance.

please check my images for more details thanks:

first of all this is first thing when i turn on my pc never had this before (but it happened with all the cases now (2 HDD plugged, The Blue one only plugged or the Green WD only too)) i guess it doesn't matter

those are my sections:

this is the C Section which contain the Windows 10 files
https://ibb.co/B4Bz4YY

this is the D Section which contain the Windows 7 files
https://ibb.co/x3rcsZH

this is a method that i found to confirm which version is installed on which driver and as you can see it's indication that Windows 10 is on the C Drive (WD Green 1TB)

as you can see it's indication that Windows 7 is on the D Drive (WD Blue 250GB)

this is where i am not able to understand the boot page is on my 1TB WD Green which as i showed you my W10 is installed but the "active system" is written on the Blue 250GB WD.

Just one thing in mind is it possible that i am wrong which windows is installed in which driver, if not please if there's anything to help me with do thanks in advance.

The sound you speak of and have shown in your video is definitely coming from the HDD, since it's showing it's age and ofc due to wear and tear. I'd advice you to reduce the number of partitions on your drives, namely the 1TB HDD, reduce it to 1 or at max 2 partitions.

You will need to back up all data before you can restructure your partitions, mind you. Also, you should've had only the WD Blue HDD attached onto the system when installing the OS, that's why the partitions were split that way.

Also, please include/list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
GPU:
PSU:
OS:

including the age of your PSU, not just the make and model or it's wattage.

Hi Lutfij thanks for your replay, sorry but i guess you missed the main request here, i don't want to reformat my PC i am really not a fan of that, my request is i want to know why my PC is not booting when unplugging the blue HDD when as you saw in the images it's installed on the Green 1T WD and not on the Blue WD,
and my specs are:
CPU: I5 2500K
Motherboard: 98Z68-V POR
Ram: 20GB (4GB & 2x 8GB)
SSD/HDD:Only HDDs as i said in the topic
GPU: GTX 1060 6GB XTREME GAMING
PSU: Smart SE 730w i guess it's like from 2015
OS: Windows 10 and i have Windows 7 on the other HDD.

Which OS did you install first?
Were both drives connected when you installed the second OS?

Also, please show us a screencap of your Disk Management window.

*Hi i really can't remember but i have the Green WD From 2012 and i had that time Windows 7 then i upgrade it to windows 10 when it was free, then i didn't like it so i delete it but the files where on a file called Old Windows after that and i have checked now i have bought windows 10 and installed it in 11/26/2019 so i guess it's a mess but if you checked my images it's really showing that my W7 is on my WD Bleu and W10 is on my WD Green unless it's not the case, i have shared the Disk Management already, please check it above

OK, just to verify:

250GB, Disk 0 is Win 7
1TB, Disk 1 is Win 10.

Correct?

yes that's what i want to believe, 1TB as the images is devided to 3 sections (C, F and G)
and the Blue is with one partition D which i believe and i am pretty sure it has the Win7.
