Windows 7: Satrtup problem....

I was messing around with the startup options in windows. I have windows 7 and Splash top OS. I changed the default OS to Splash top OS from the windows 7 startup options and unchecked the button "Display list of options for..."

Now my PC directly boots to splash top OS. The boot selection screen only popups for a millisecond. I have already tried pressing escape and f8 but to no avail. I know it can be repaired by windows 7 installation disc but that is time consuming. If any body knows any other way then Please help me.

i don't know much, but it may help.

Click Windows Orb > Search for "System Variables", and click on "edit the system environment variables".

Under the Advanced Tab > Startup and Recovery > Click Settings

Change your Default Operating System. If this does or not solve your problem, post back.

OP can't boot into Windows 7 presently.

You'll need to find similar settings in the booting OS for changing the default OS at boot.

If not, mark Windows 7 partition Active, run Startup Repair repeatedly to start Windows 7, then add the other OS to Dual Boot using EasyBCD 2.02 or similar program.

I think that is a long way. It was a good thing that I have windows 7 installed on a separate partition and all my data on other. I'll just format that and reinstall windows.
