well i tell u indetails....
I have 80GB HDD with 10GB each C, D, E, 15GB F & G and a 20GB H partition....
the pramary dos partion is drive c:.... all otheres r logical drives....
C, D, E, G is in NTFS format..... & F, H is FAT32.....
now i had wind2K Server SP4 install in C: & winXP Pro SP2 in drive d:....... some times back i installed win Server 2003 SP1 (Fresh install, no upgrad...) on the c: drive....
system didnt had any problem of ditecting the OS change... BOOT.ini changed it self to config as for those to new OS....
well when i wanted to return to the win2k SP4... i just went with a quick format of the drive c: & install the fresh copy of the OS.....
as win2k is elder than XP thats why i lost the dual boot menu...
so i tryed this.....
Fixboot, fixmbr, bootcfg, copying the ntldr & ntdetect.com from xp sp2 cd...
earlyer i tryed this with FAT32.... there it worked.... but with NTFS i get this error.....
ntldr is compressed
press ctrl_alt_del to restart......
