After installing the new OS onto your SSD, you'd need to format your old HDD, if you want to use it as a storage medium.
If not, you'll have 2 OS to boot from, and you need to select which one to boot into everytime you login, and you might not be able to access files in different medium.
This situation can be eliminated, there are ways.
And to delete an OS, yes, you have to clean format a Disk.
If you want your OS on your SSD, and HDD purely for Storage purposes.
You can do that.
or
You can connect both SSD and HDD, and in your Boot screen, select boot medium to CD/Thumbdrive so that you install your OS through boot and not in windows.
Select to install OS onto SSD.
After installing, you'll most probably prompted to boot into either of the 2 OSes, boot into the one on your SSD, and from your OS in SSD, reformat your HDD.
NOTE
Backup important data on an external medium before reformatting your HDD, cause once done no return, any media files which can be redownloaded or important documents etc.
Ok understood. Thank you so much for your help.![]()
Sorry to hijkack, but I'm currently using a SSD with OS installed now.
Lets say if i want to upgrade my mobo and processor, will need to reformat it right?
Any settings that i need to change from BIOS prior to installation? (coz i heard need AHCI or something like that, sry I'm noob)
By doing this, TS will end up with a half bake O/S.You can connect both SSD and HDD, and in your Boot screen, select boot medium to CD/Thumbdrive so that you install your OS through boot and not in windows.

By doing this, TS will end up with a half bake O/S.
The installation routine will check and detected an existing (HDD) active,primary, boot and system partition and promptly install %system% into the SSD and will not set the SSD as active, boot and system partition. If the HDD R.I.P or removed, TS will end up with a non bootable system even though %system% reside in it.
Is there any better method for my situation?

CLONE. Save time and will work fine 1
after clone liao then wipe the hdd and use
Not very familiar with this process. I need to spend time to read up on it.

clone and to ssd.
use clonezilla
remember set the ssd to AHCI mode,
I can do the other method by reformatting my hdd. Then disconnect the hdd and connect a ssd and install new OS. After OS installed, connect my hdd for storage. Will there be any problem?
By doing the step (red words), TS will end up with BSOD STOP:0x0000007B
Connect only the SSD and change the SATA controller to AHCI in the BIOS, proceed to clean install the O/S. After O/S installed, connect the HDD to the system and proceed to format it after backup all required data.
If the HDD been using for a couple of years or filled with hell load of junk, don't bother to clone the HDD to the SSD. Clean install the O/S is the best option IMHO.
