Short answer: yes — two physical drives each with Windows 7 can live in one PC and you can either pick which to boot from the BIOS/boot menu (fast and safe) or install a proper dual‑boot menu so the machine shows both OS choices at startup.

Practical, safe workflow:

  • Back up both drives first (they contain important files).

  • Decide which physical disk will hold the Windows Boot Manager (the “system” disk). Boot that Windows normally and make sure the other Windows partition is visible (assign a drive letter in Disk Management if needed).

  • From an elevated Command Prompt in the OS that will host the boot manager, add the other installation to the boot menu with:

    bcdboot D:\Windows /s C: /f ALL
bcdedit /enum

    (replace C: and D: with the correct letters). That creates a menu entry you can test at next boot. If you prefer a GUI, tools such as EasyBCD can do the same.

If the PC restarts immediately when you attach the second drive (your reported symptom), troubleshoot before changing boot files: check power and SATA cables and ports, confirm the BIOS actually detects both disks, try each drive alone to verify they boot by themselves, and test the second disk externally (USB dock) so you don’t alter the internal boot setup — suggested a docking approach. Also consider cloned drives or SATA mode mismatches (AHCI vs IDE) as possible causes and test by switching ports/modes or by disconnecting one drive and booting the other.

If the Windows bootloader is damaged, boot from Windows 7 media, choose Repair > Command Prompt and run:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

For a quick selection at power‑on use the motherboard boot menu/BIOS as and note; ’s point stands — one drive will be the default boot device unless you change it. Note: Windows 7 reached end of support on January 14, 2020; consider migrating to a supported OS for security updates.

Please explain what you want to do with them, except whether or not you can put them both in 1 computer. The answer to that is "of course". One will be the system/boot drive. The other a data drive, unless you instruct the BIOS to boot from the second drive.
