Question: Hello there.

I recently bought a 9.5 mm HDD caddy and 120GB SSD for my laptop to make it a bit faster. I screwed the SSD into the caddy and put it in the laptop. Then I installed Windows 10 on it. So now i had 2 operating systems (1 on each drive). I tried to wipe the HDD after backing up some of my data as i didnt need 2nd os anymore. I tried diskpart to format it but didnt work saying something like “Disk 0 cannot be formatted.”. So I just take my laptop apart and formatted it using another pc. After that i was no longer able to boot on SSD anymore which I still dont understand why. While I took the laptop apart I decided to install the SSD in the internal SATA connection and HDD to caddy. Installed a CLEAN windows once again on the SSD. But Then I realized my HDD wont fit into my caddy (too thick SeaGate 1TB SSHD). I was able to put it in but it was too much tight fit that I felt uncomfortable.

My question is that will i still be able to boot windows from SSD if i swap their places back (SSD to caddy / HDD to SATA).

NOTE: BIOS WAS NOT ABLE TO RECOGNISE CADDY AS A BOOT DRIVE WHEN I FIRST INSTALLED WINDOWS 10 ON IT .

Answer:

Bios verison is:
American Management inc. F.32, 25.04.2019 (Latest verison manufacturer supported.)
Laptop Model is HP PAVILION aw007nt

I have a clean windows on Sata SSD. What i am trying to do is take that SSD and put it into CD-ROM caddy, So I can reuse my HDD as secondary storage unit. Question is that will I still be able to boot from SSD if I connect it to caddy? I tried to change boot order but only thing popped up was the one that connected to on board SATA. Also before when i didnt do any of those,, I was able to boot on SSD caddy while the EFI and recovery files were still located on the SATA HDD . Things got nasty when I backed up my data and completely wiped that whole HDD partitions. Then I was not able to boot from neither Caddy nor internal SATA.

I am replying and solving my own problem since no one helped to solve it.

When I connect the SSD to CD-ROM and installed windows on it, SSD used the HDD’s EFI partition to boot on SSD. So when I format the HDD I was no longer able to boot from SDD. After I reinstall windows this time the EFI and Recovery partitions got written on the SSD and my BIOS was able to SEE it as a boot drive no matter if it is in CADDY or INTERNAL SATA.

So answer of my queiston was “YES YOU CAN USE CD-ROM CADDY TO BOOT WINDOWS.”(If you do it properly)

Thank You, hope this helps someone…
