On most systems, pressing F12 at boot up will get you a menu to select where you want to boot from.

Give that a try.

Hi and Welcome to SevenForums,

You will need to change the boot order in the bios or depending on the make of laptop/desktop you have you may be able select a boot device by pressing F9 at startup.

Can you please fill out your system specs so we can see what hardware we a dealing with.

Regards,
Jamie

Tap the key given for your model PC, select DVD drive to boot:

Asus - F8
HP/Compaq - Esc
Sony - F2
Acer - F12
Gateway - F10
eMachnes - F10
Toshiba - F12
Dell - F12
IBM/Lenovo - the blue Thinkvantage button

This is a great list Greg.

Just to add if it's of any help, we use HP's at work as the primary Manufacturer and F10 seems to be the default for the BIOS or you can press F9 to select a boot device (more of a one time thing rather than chaining the order).

Regards,
Jamie

Take a look at this video, it's not the clearest, does your look like this?

Look from 1 minute 15 seconds, this is where the boot sequence is.

On Dell use F12 to choose boot device, run hardware Diagnostics to test hardware.

If the bootmgr compressed fix doesn't work, try System Restore to before you made any changes from the disk's System Recovery Options.

Try also a few Startup Repairs as suggested earlier, after confirming the Partition Marked Active .

If you decide to reinstall you can run Dell Windows 7 PC Restore or do the superior Clean Reinstall - Factory OEM Windows 7 . Be sure to read the Special Note to Dell Owners at the end about what partitions to save, and notice the step to rescue any files needed first.
