I'm thinking about installing Linux alongside my Windows setup, but I have some questions. First off, I want to know if it's possible to install Linux without losing any of the data I have on my hard drive. I currently have Windows installed on my SSD and a separate 1TB HDD. If I disconnect the HDD during the installation, will that keep my data safe? Secondly, do I need to remove BitLocker if I'm not planning on dual booting? Lastly, I've been getting a lot of BSOD (Blue Screen of Death) errors in Windows, and I'm wondering if switching to Linux will cause any issues if there's something wrong with my hardware that's causing the BSOD in the first place.

I’ve switched between Linux and Windows a few times without losing my files, but I’ve also messed up due to not following steps carefully. If you follow the installation instructions well—especially regarding not formatting NTFS partitions—you should be fine. Just remember, there's a chance to mess up during partitioning, so do your research before diving in!
You actually don't have to remove BitLocker to install Linux, but it's generally a good idea to do so, especially if you're making significant changes like replacing the OS. If your hard drive is encrypted, make sure to decrypt it in Windows before you switch to Linux. And keep in mind, if you're dealing with hardware issues like BSOD, changing your OS may not fix the underlying problems.
To clarify, adjusting partitions is key. You can install Linux on an empty partition by using the space you create—just be extra cautious not to touch or format your NTFS drives during the installation process. If you want a smoother experience, disable Windows Fast Startup and hibernation first. And yes, you should definitely back up your data; there's always a chance things might go wrong during the partitioning process!
Yes, you can install Linux on your SSD without affecting your HDD, but it's highly recommended to disconnect the HDD during the installation. This way, there's no chance of accidentally formatting it. Just remember, when you install Linux on the SSD, it will format that drive, so make sure you move any important files off of there first!

But if I have BitLocker enabled on a partition and I install Linux, will it wipe the data on that partition or just remove BitLocker? Also, is it fine if I skip dual booting?
