Unmountable Boot Volume after reassembly

[Dom_Uchiha]

I opened my laptop to clean it following a guide on youtube. I put everything back and ran it once before putting on the back cover. After seeing the login screen, i shut it down, put the back cover, screws, and turned my lappy on.
I got the unmountable boot volume blue screen
I have tried reinserting ram, hard drive (it doesnt have wires, direct plugin), checked for loose connections.
The hard drive shows up in bios, even tried changing between ahci and ide.
Lenovo y510p with win 10
Please help!

[Update]
I formatted my c drive and installed a fresh copy of windows.
Seems like it had nothing to do with my cleaning.
The world just trolled me hard.
