Hi

I have two hard drive( Samsung & Seagate) on my PC with single partition (OS window XP)
Both of drives has operating systems.
When I boot PC with Samsung hard disk, it shows the seagate hard disk as D: drive
But when I boot the PC with Seagate hard disk then again it shows the same seagate as D: drive & Samsung as C: drive

Can any body help me

Definitely maybe. Drive letters are configured, while logged in as an Administrator, via Start > Control Panel > Administrative Tools > Computer Management > Storage > Disk Management, then right-click a partition and choose "Change Drive Letter and Paths...". The system partition actually being booted from is noted in Disk Management too. The hidden BOOT.INI file in the root of the drive(s) can also be viewed to see which Windows installation gets loaded.
