Do I need to edit the MBR before reinstalling windows 7 on non-system drives?

Question

System administration

And do I need to disable disks that are not system or what is the right way?
What exactly will write the MBR chain?
Does Windows 7 itself edit the MBR after installation, boot. when hard drives are added from another computer or previous system, or is this done only when installing Windows with its installer?
Sorry for so many questions, but they are all related to the same thing.
I want to reinstall Windows correctly for the first time in my life.
Before that, I set it as it would turn out and if only it worked, it is worth noting that I worked for a long time and didn’t ask for food. But it’s time to do everything right. I ask for help or an answer if I will do the right thing by doing as I describe.
On a computer with BIOS - 2 system disks, "seagate" and "VD".
- On the Seagate, the XP bootloader, sevens and the XP system, WIN7 OS, in addition to the bootloader, is located on the HD.
I plan to delete the info from the Seagate, I saved everything from there for a long time.
On the VD there is still infa from the system program folders, which will need to be saved.
On the remaining FIVE screws are the files that I need. The sections are all basic. The NTFS file system.
Question:
Do I need to edit the MBR on five non-system drives BEFORE reinstalling Windows?
Sorry, I'm not an expert and I don't understand how it works in detail, i.e. I want to do this:
- Save all important information from system disks;
Physically remove all connectors of non-system disks, boot from a USB flash drive, format and partition the former system hard drives from portable Windows using its regular means (make three or 4 main partitions on the system disk of the VD). Seagate disk with bads, so format it and remove it from the system. Next, after installing Windows, connect back 5 hard drives with data. After connecting them, as far as I understand, the MBR will be overwritten by Windows? or will it stay the same? in general, I have a misunderstanding, but the computer is used all the time. You will also need to turn on ACHI, it seems that it was already turned on but then turned off, I forgot already where there might be troubles.

Не нужно править. Если что, винда сама поправит.
MBR содержит информацию о разделах дисков. Он меняется,если ты меняешь разделы.
