Two drive C volumes?

Hi,

Further to your very helpful comments regarding the installation of a new SSD - with 64-bit windows 7 home premium on - the disc is now up and running - and lightening fast!

However, I have a problem!

Having unhooked the two HDD's I have, then setup the new SSD - the new install has labelled the drive as 'C'. This is the problem - as one of the HDD's is also a 'C' drive - so my idea of connecting them both and using F8 to select the boot device now won't work.

Upon completing the install of Windows 7 - I checked online about how to re-assign the drive letter. I tried to do it using the 'manage devices' option - but the system would not allow me to change it from 'C' to any other letter.

Is there a way to do that with the SSD - so that I can use F8 to select the SSD or HDD and boot to it - without affecting the other device? I don't necessarily want to access the HDD's while using the SSD anyway - but it's going to be a paid having to physically unhook the HDD's every time I want to boot to the SSD.

I'm sure it's just a stupid mistake I've made when setting up the new installation, but any help would be appreciated.

Thanks for the quick response.

The system is an AMD Phenom II 955 BE one based around an Asus motherboard.

My only concern about the SSD taking C - is what happens to the other C drive (the HDD one)? As I use this drive as my 'primary drive' for emails and such, I don't want it to be assigned a different letter and change paths etc? If it does that, then I try to boot to it the next time - does it change back to it's proper C drive and all the paths are unaffected?

I just can't afford to loose the data on there - but at the same time, I don't want to mess around having to unplug hardware each time.

Sorry - I forgot to say - yes, F8 gets me to the boot manager for the system and brings up the list of drives. It was a little strange yesterday when I put the machine back together and my old XP drive booted first - and that is now only used for storage but still has the windows folder on it! (Which has now changed!)

So, with some confidence, I could install the other drive, and boot either to Windows 7 32-bit on the HDD - which will retain 'drive C' status and work fine.

Or, I can boot to Windows 7 64-bit onthe SSD - which will then take over as 'drive C' and allow me to use it - without loosing the data on my HDD drive C?

That would be great news!! (and thank you for the helpful comments)

I used to dual boot Windows Vista and Windows 7.

Whichever system I booted into was allocated drive letter C and the OS not being used was allocated drive letter D and vice versa.

As whs rightly says, sharing data folders between the two system drives is a doddle so you should be perfectly OK with your setup.

As an aside, I'm thinking of getting an SSD. Is it worth the extra expense?

Thanks again guys - with a little bit of re-assurance from another colleague, I hooked up both drives and they appear to be working fine - switching the drive letters as I boot.

Seavixen32 - I paid £79.99 from Ebuyer . com for this Kingston V100 60gb drive - and if I'm honest, the load times, reboot times and program responsiveness is pretty awesome - I would get one.

whs - another question for you now - sorry about this - I sound like a proper nooblet!

Having discovered that I didn't have AHCI enabled on the m/board but should be using it to get full advantage of the SSD - when I turn it on, the OS bluescreens! I've read on the net that you can stop this by editing the registry and changing the msahci value to 0 - it's currently 3.

Whilst I'm happy to try this on the new install on the SSD - I also have the original install on the HDD. Is there a way to change the registry on the HDD while booted into the SSD, or visa-versa - so that I can change both. Otherwise, is I change on the SSD, when I boot to the HDD, it will BSOD - and it will mean switching AHCI off in the BIOS to get into that system.

What would you recommend? I though one work around would be to change it in one drive, leave it disabled in the BIOS, then boot to the 2nd drive (still in SATA mode, not AHCI) and change it there - then, reboot again and enable it in the BIOS - and hopefully, when I then boot to either drive, it should recognise AHCI and install it / work okay?

What do you think - and do you have any 'easier' suggestions?

There is a forum's tutorial on how to change to AHCI after install: AHCI : Enable in Windows 7 / Vista

In a dual boot where both must be changed I think I would remove the other HD while I change over the first one, then repeat the same with the other HD set to its native SATA mode to start.

As I've not done this myself, I'd wait for Wolfgang or the tutorial author to sign off on it before proceeding. Also, other than the ability to have modern hotplugging there are no reports I can remember of improved performance.
