Windows 7: Local drive is H not C?

Local drive is H not C?


I have just upgraded to Windows 7 from XP.

Everything is working OK but My hard drive letter is now H not C

Why has this happened?

Is it an issue?

I'm concerned that it will mess up my iTunes library and generally confuse things.

This can sometimes happen when doing an upgrade type install from inside an existing OS.
The only sure way to prevent this is to install fresh from external media

The best way to deal with a dual boot is to keep all your data on a separate data partition which can then be assigned the same drive letter from within both OS's.

You can then store things such a the iTunes library and your documents on the data partition - a secondary benefit of this policy is that if you lose an OS you are less likely to lose or corrupt the data

If this is a single OS situation then it should not cause any issues for correctly written software and their installers - however a program that assumes a system drive is the C: drive may have issues

you can change it back to C by right clicking the Computer icon and choosing Manage. Click Storage, then Disk Management, right click the H: drive and change it from there.

Barman58 this is only a single OS not dual boot.

winsev I have have just looked at the computer management now, thanks.
However when I go to change it a warning window pops up saying;

"Some programs that rely on drive letters might not run corrrectly. Do you want to continue?"

Is this going to mean an OS reinstall?

Hi Wookie,

Sorry for any confusion, If you have only just installed the OS I would suggest that a re-install would be the best solution.

Although the problems that you may encounter if leaving as is would most probably be minor, there is no guarantee that one of these minor problems could cause you personally a major issue - we all use the PC differently.

If you check the Tutorials section here you will find various options you could try to keep inconvenience to a minimum - especially if you have installed a lot of programs.

Things such as a repair install or upgrade may re-set the system drive to C: but I cannot confirm this, from experience.

The option of a complete fresh re-install is always going to be the best option but only you can decide if this is viable for yourself

Thanks Barman58,

I knew it couldn't just be as simple as changing a setting.

Going to bite the bullet and change it
