you have to tinker more, but work on a pc dedicated/specifically to avoid damage and gain experience.

First, gather.

Ventoy
Rescurezilla
Gparted or Partition Magic


for medicat it's early...

Just disconnect your main OS drive. Then install OS to new drive. You have to boot to the new anyways to complete the install process. Once the new OS reaches the Desktop you can do a proper shutdown. Then reconnect the primary OS drive. But on the next power on, enter the BIOS and make the primary OS drive either 1st or the only boot drive.

secure boot should be disabled to avoid surprises perhaps.

yes, just remove all other drives during each os install so all os partitions are on the same drive

when complete, plug in both drives, and use bios to pick the drive to boot from
f8 on most boards will bring up the boot select menu

any operating system loaded as needed. https://ibb.co/609Cb3pp

As already mentioned, disconnect any other drives before installing to that other drive then plug the other drive back into its original location with the 2nd drive in another Slot/SATA. installing with both drives connected may cause Boot Manager issues down the road, though may not be as much of an issue these days, but still, separate is best.

A good operating system has a default boot menu at startup, purposely allowing a few seconds to choose whether to load itself or another detected source, such as a USB port or something else. Keep rewarding PikaOS. All systems should do the same, regardless of which one starts first in the boot order.

You don't want that non sense. Just have each drive and OS as independent so you can pull a drive as needed and not have OS' see each other. Especially in scenario such as this. Simply use BIOS F# key to select boot drive at POST. But that's only even needed if you boot to the OTHER Drive/OS not the default one.

got a second SSD with games.
It works. Just select the drive in the settings as default. Got a large capacty ssd in there.
Can format the computer. Then change the drive in the settings. Your games are still there and no need to install again.

thats for games or programs, not a separate os

ex. installing win 10 on one drive and linux on another
use bios to set one drive as default, at post pick the other drive

then if you ever need to wipe or remove a drive you can do that without hurting the other os install

Did you read anything at all?

Yea you don't do that when you want separate drives with separate OS'

I like to keep the Operating Systems close to each other in SATA 0 and 1. Make sure if you can run RAID or similar instances, that the SATA port used is bootable (mine is only bootable from SATA 0-7 but not RAID 0 and 1; aka SATA 8 and 9)

Another odd thing about this old board is that they state in the manual, SATA 1-8 (bootable) with 9 and 10 unbootable, excluding SATA 0 altogether. I guess, it is just easier for the common user to understand 1-10 instead of 0-9 being 10 SATA ports in order from top to bottom.

Putting the Operating Systems on closer SATA ports takes the brainwork out of routing the cables and guess work outta knowing which is which in the long term.

I would personally hate to have to route the cable for Win10 on SATA 1 and then Win11 on SATA 6 as down the road I may need to reroute those SATA for some reason or another.

Easy enough to change SATA instances but if you are fine with having spaced SATA, all is good - I have OCD and plenty times I needed to reroute SATA to fit my means (I run 20 SSD/HDD drives with 10 being Hot Swap - do not even ask about my newest upgrade).

What I have found interesting though is that 1 SATA power cable is enough to power 2 SATA SSD/HDD drives which was a lovely surprise overall when splitting.

SATA port locations do not matter unless the MOBO cannot boot from specific SATA ports such as my RAID ports.

The only warning I will give to you, OP, is please do not clone Win10 and then move to Win11 on that clone because you will run into an issue but you can use the same Win10 key to activate Win11 (while keeping Win10 still activated without issue).

I only speak about retail keys, never OEM; although, I own one OEM key on the laptop. I have done zero research on migration of OEM Windows keys nor dual-booting from an OEM Win key.

It doesn't even matter, SATA is SATA. All that might change is how they are listed in the BIOS.

Modern Motherboards only have maybe 2-6 SATA if you are lucky when you don't have a PCIE card.

Or if actually doing a RAID and need to ensure all the RAID drives are on the same chipset, since most boards might divide the ports across two chipsets.

I mean, if you are only working with say a few disk drives, it is far easier to route the cables and know which cable is which but when you are running 10+ SATA cables, it tends to get confusing. I even named my SSD/HDD docking bays by drive letter and SATA port in the back of the case area for easier sorting and location.

When I was attempting the dual boot, it was just easier to have SATA 0 and 1 as respective Win11 and Win10 but I had to reroute Z drive (SATA 7 to SATA 3) and Y drive from SATA 0 to SATA 8 to install that SATA 0 (Win11) closer to Win10 (SATA 1) so now I know the top 2 SATA ports are OS and never to touch/pull those in the future.

When you are running a PC like a ♥♥♥♥♥♥♥ server, ♥♥♥♥ can get a bit confusing.

*snip*

to boot from a raid drive, you need to install the raid driver when installing windows
get raid driver from the mobo mfg site, unzip it to a usb stick
during the os install, when it asks to select drives, add the driver and then the raid disk will appear on the list and you can use that for the os

and it makes zero difference what sata ports are used, bios can select any port for the drive to boot from

it only makes a difference when setting up the raid array

but the op is not talking about raid at all, its 2 separate drives with 2 separate os installs

This isn't XP or Win7... 10 and 11 have all that built in.

However to boot from RAID it has to have a ROM option for that.
