On slayers how can i go back to the main screen from and app. with out rebooting, is there a way to do this? Thank you for taking the time to answer my questions.

Load slayers disk then use option 9 (i think)

9) If you get Error21, and the M$ Dashboard does not start up, follow the steps below:     9-1) Eject the DVD tray and insert the Auto-Installer Media     9-2) Power ON/OFF to boot from the media (MOD still ON)     9-3) Select Option (3-4) to Replace the M$ Dash with the alternate version, 4627     9-4) Eject the DVD tray and remove the Auto-Installer Media     9-5) Power ON/OFF to boot from the HD (MOD still ON)     9-6) Repeat Steps (6) and (8) above and verify the M$ Dash Starts up OK     9-7) If you still get Error21 you have 2 choices:         9-7-1) Repeat step (9-3) with Installer Options (3-5) & then (3-6)           OR         9-7-2) Restore from your backup of the C: drive 3 files and overwrite the ones                 on the Xbox HD in C:  The files are:                 xboxdash.xbe (which you'll need to rename to msxboxdash.xbe), Memory2.xip                 and default.xip     9-8) Repeat Steps (6) and (8) above and verify the M$ dash Starts up OK

yup I was right. If you need more help open Install Instructions v2.0 it's a msinfo just use word pad to look at it. All the answers are there. Are you getting error 13 or 21. error 13 uses step 18

I got the same thing when I chose the upgrade option from Slayer's 2.1

I then chose to rebuild the HDD and it worked just fine.
