u can boot to ur previous windows
read carefully
1. right click my computer n go to properties
2. go to advanced->startup n recover settings
3.u will see an option to edit boot.ini file
4. select edit button
this is my boot.ini
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /noexecute=optin /fastdetect
in ur u will find partiion to be different
say if u installed in 2nd partition
it will be like
multi(0)disk(0)rdisk(0)partition(
2)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
so u add another line
multi(0)disk(0)rdisk(0)partition(
1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
1 because it was in first partition b4
save the file n restart
u will se 2 options for windows n u can boot into ur previous one
Note u can chg the name that will be displayed
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="
Microsoft Windows XP Professional" /noexecute=optin /fastdetect
if u chg that name it will display ur new name in list
when i did this i used these names to differentiate
Microsoft Windows XP Professional
Microsoft Windows XP Professional old
Remeber this is not for the weak hearted guys who r scared to edit such files
