How do I install W10 on second SSD for dual boot system
I've found conflicting recommendations on whether it is necessary to unplug existing drives when installing Win 10 onto a second SSD. Desktop was drive 1 SSD (C:) and drive 2 HDD (D:) until I installed a second SSD to become (D:) so it will become:
1st drive > SSD (C:) with Win 7 on it.
2nd drive > SSD (D:) new/blank drive I'm newly installing Win 10 onto.
3rd drive > HDD (E:) with only data on it (never any OS).
Will install Win 10 from an iso on a CD. BIOS/UEFI (unsure of terminology) boot order was already set as:
#1 cd drive
#2 1st SSD (with Win 7)
#3 2nd SSD (new/blank) - I checked and it IS listed.
So, I'm trying to make sure I can dual boot AND the system is bootable even if one of the drives is removed at some point plus be sure that the drive letters assigned (as above) don't change. Another potential wrinkle is in disk management originally disk 0 was the SSD (with Win 7 on it) and disk 1 was the HDD (w/ no OS). After installing the new/2nd SSD (left SATA cable to 1st SSD as is was and just moved the other SATA cables down a notch so to speak) - but now it shows as new SSD as disk 0, original SSD as disk 1 and the HDD as disk 2. It is for sure connected to MoBo as: disk 0 = original SSD (w/ OS), disk 1 = new SSD, disk 2 = original HDD, disk 3 = CD drive.
Should I disconnect drives 1 and 3, then install Win 10 on drive 2 and reconnect other drives once Win10 after is up and working OR just leave all drives connected and install Win 10? If disconnect then from the MoBo end OR from the drive ends?
Thanks!
