Crosses 1024 cylinders - Not bootable??

[LocoPollo]

I'm trying to shrink a partition, that I made when I installed windows. But when I try it says "This partition crosses the 1024 cylinder boundary and may not be bootable" - however it IS bootable right now, and its 80! I have to go below 8gb before it doesn't say that.

So what is this all about?? I have had alot of bootable partitions that were bigger than the 8gb, so this is new to me, and now I dont have a guts to do it.

Can anyone tell me if the partition will work if I shrink the partition from 80gb to 15gb? and if it will, why do they write this?

(I want to shrink it to 15 gb, and make another storage partition.)

Thanks!

Other and/or earlier operating systems were limited by the BIOS to have a boot files in the first 1024 and if in program manipulation they got moved beyond the 1024 the BIOS couldn't get to them to bring the system up.

Since your current OS didn't have any problem with the 80 it shouldn't have a problem with the 15. Suspicion that the reason is your current OS takes control of the HDC earlier in the boot cycle.

This software is free to try and includes a resize option.

If I bootup into DOS and use the DOS version of Partition Magic (for example), you get this "error" when performing partition operations. Since you are running Windows XP, as edfair suggests you have nothing to worry about. In my example, the "error" appears because I am booted into DOS and DOS is limited by the 1024 cylinder rule

Sounds like you are using 'Parition Magic'. This message is only a minor warning and not really signifigant. As long as the critical boot files (boot sector, boot loader, and system kernal) are within the first 1024 cylinders of the drive, then the system can boot. Windows typically locates these critical files as close to the start of the drive as possible (as they are usually the first files to be written to the drive at installation), and they are typically not re-located during Parition Magic's partition resize operation.
