I have a similar question and would love to know if anyone has any recommendations. I have a MacBook Pro 5,5 mid-2009 running Catalina 10.15.5. Is there anyway to dual boot macOS and windows within the same HDD? or do I have to have two separate drives? Thank you all for your amazing work on helping me to bring life back into this old machine.
@Muhammad009, I used boot camp and it worked for me with no issues. I had to download a Windows 10 ISO and create a bootable DVD. You also need a flash drive for the post install updates. More info and quick video below.
Windows 10 with Boot Camp...... After reading a few posts that stated people were unable to boot back to the Apple Volume after using Boot Camp to install Windows 10, I decided to try something
I wanted to install windows 10 using boot camp and add that that as a 2nd drive to my 2010 15" MBP, so I can boot to either hard drive. After I got Windows up on that drive, I decided to see if I could boot back to the Apple Volume.. and BAM, it worked.
So, feeling lucky, I backed up my main drive on my MBP (you know, in case I mess up) and decided to try to this on there, too... BAM it worked.
I uploaded a quick video of it booting back and forth...
Now, I'm not saying to try this on your computer but if you try, BACK UP YOUR COMPUTER 1ST, just in case.
