How to install Linux Mint next to Windows 7 if it doesn't see it?

Question

linux

The question is. I can’t install Linux Mint as a second system next to Windows 7.
The Linux installer does not see the previously pre-installed OS, and therefore there is no possibility of automatic installation next to it (as shown in the screenshot).
Initially, I installed Windows 7 on a laptop with a 500GB hard drive, after completely formatting the entire hard drive in NTFS format (by default). Created two partitions of 100 GB each and installed the system.
After booting into Linux Mint from the boot disk in the Devices item, Windows partitions are visible: 104 GB Volume - on which the OS is installed, the second one is not displayed, because. it has not been formatted yet, and the third is a partition reserved by the system, larger than 100 MB. That is, Linux sees the marked partitions.
When opening the GParted utility, a “Libparted warning” appears, and then writes that the entire hard drive of the computer is not partitioned. I understand that if you continue the installation, then Windows will completely crash.
I don’t know what to do, I’m installing for the first time, I used only Windows before, but now I want to completely switch to Linux. I just need Photoshop and Sony Vegas, which is why I can’t completely demolish the previous system, all that remains is to put them side by side. I did everything according to this instruction , but something went wrong.

Answer 1

You have a zoo of partitions, why is it done like this?. Delete all partitions, run the Windows installer, create one partition, but not GPT, but MBR at the beginning of the disk for 100 gigs (well, or how much you need under Windows) Then install Mint.
Or you can make the necessary partitions in the same GParted, then install Windows, then Mint.

Answer 2

using unetbootin on a flash drive, upload xbutnu. Then start from a flash drive and in a couple of mouse clicks you will put it next to Windows

Answer 3

You have a rather interesting case) Apparently, you had it visible on GPT, then you put Windows on MBR. GPT is such a thing that is quite difficult to clean from a disk and Windows does not bother with this, so you now have a valid msdos and an incorrect GPT. In short, in the third screenshot, you need to click No (Is this a gpt partition table?), and everything should be fine with you)
