Re: second OS disseappeared from boot list

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

We need to know your disk and partition layout. Or you can try with the Bootcfg command from the Recovery console.

For a computer with two hard disks the following would allow you to boot from 4 partitions on each disk:

[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="Windows 0,1" /noexecute=optin /fastdetect"
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows 0,2" /noexecute=optin /fastdetect"
multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Windows 0,3" /noexecute=optin /fastdetect"
multi(0)disk(0)rdisk(0)partition(4)\WINDOWS="Windows 0,4" /noexecute=optin /fastdetect"
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Windows 1,1" /noexecute=optin /fastdetect"
multi(0)disk(0)rdisk(1)partition(2)\WINDOWS="Windows 1,2" /noexecute=optin /fastdetect"
multi(0)disk(0)rdisk(1)partition(3)\WINDOWS="Windows 1,3" /noexecute=optin /fastdetect"
multi(0)disk(0)rdisk(1)partition(4)\WINDOWS="Windows 1,4" /noexecute=optin /fastdetect"


Above also assumes that Windows is installed in the \WINDOWS directory. The text between the quotation marks (like "Windows 1,4") doesn't make any difference, it's only descriptive text for human eyes, you can put what ever you want for the descriptive text, in the file above it just refers to the disk and partition numbers. The all important information is in the ARC paths such as:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

I have XP SP3 in Primary Partition. Server 2003 ENT in secondary Partition. Earlier I had the option to boot from anyone at start-up of system. Now I don't see the Server in the options to boot from.
Disk Management shows it.
My Computer shows it as well.
I can even explore it from XP and see all programs and documents.

This is a copy of what I see in Settings>control panel>system>Advanced>>>Edit : startup and recovery

"[boot loader]

[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect"

Anyone Please?
If it's (Server 2003) on the second partition on the same disk as Windows XP:

[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" /noexecute=optin /fastdetect"
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Server 2003" /noexecute=optin /fastdetect"
