no there was no any warnings while or after the installation. Instead, the computer rebooted and showed the dialog that the installation was successful.
ya i tried connecting pen-drive in the USB port but didn't detect. The main thing is the USB itself is not being detected in my system. Not in the Device Manager, Not in the BIOS setup, not even when i tried to find it running the msinfo32.exe file.
thinking that if its a problem of OS, i formatted my computer and re-installed the OS but same problem persists. Now, i feel its not due to the malfunctioning of OS coz nothing is shows in the USB Configuration in BIOS setup itself.
I took it to the computer mechanics too but they too couldn't figure out.
Can it be the problem of the driver of USB ? coz I never used the USB port infront of my CPU. When I tried using it getting it connected by the hardware mechanic that USB port was also not working, ie. wasn't detecting the device connected.
regards,
Jay
