hi I installed a 120gb seagate hdd in my xbox and now I can't boot up the original msdash dash [using eject button instead of power] I get a screen with garbled green writing in spanish or something?

with a couple of black 05's over the top on the left [error code maybye]I think It might be saying something about not reconising the hdd but im not sure

. the hdd works fine of the modchip, with evox.

but I can't understand why it [orginal msdash]doesn't work now,

as I copied all the original files back to C: & E: I used to be able to boot either dash before I installed the new hdd . I saw a file in the backup folder called hddinfo.txt that has the model No. & Serial No. of the old hdd on it with a couple of lines/strings below with letters & No's I checked it again & it still has the old hdd info would changing the model No. & serial No. to the new hdd' No's fix it or do I have to change the string of No's & letters below as well ?or has hddinfo.txt got nothing to do with my problem? I use a apple-x 3 modchip & evoxdash & xboxdash.xbe to boot from
