Answer 1

You might have to edit the boot.ini file.

1. Right-click My Computer, and then click Properties.
-or-
Click Start, click Run, type sysdm.cpl, and then click OK.
2. On the Advanced tab, click Settings under Startup and Recovery.
3. Under System Startup, click Edit.

Once you open the Boot.ini file, you can edit the timeout to be say 5 (secs)
And remove the entry for windows xp professional.

This is a sample of a default Boot.ini file from a Windows XP Professional computer.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
This is a sample of the above Boot.ini file with a previous installation of Windows 2000 on a separate partition.
[boot loader]
timeout=30
default=multi(0)disk(1)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(1)rdisk(0)partition(1)\WINDOWS="Windows XP Professional" /fastdetect
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Windows 2000 Professional" /fastdetect

hope this helps.

Boot up you XP from your system disks and when you get a command prompt type:

fdisk /mbr
