I have often heard that keeping a system in dual-boot makes it run slow. Plz tell me whether this is true or not? If yes then why?

It mainly depends on the system rather than blaming dual boot configuration. Mostly not much speed difference is noted since you are loading only 1 OS at a time. People have said that it made their systems slow but only blame in those cases is system not being powerful enough.

Ask them to explain how does that happen?

I don't see how dual booting can make any system work slower. It only increases ur startup time.

most ppl think that if they'll install more OS in their system, there will be more data on the hard disk (which is usually one in most of the system).
Thats why they are afraid of the performance decrement. But thats not true.
Dual boot never slow down any system coz u run one OS at a time. ;) (and don't say about vmware or virtual pc :D )

EGGJACTLY.

Why would dual boot reduce performance. Same thing as one OS, just that two OS on different partitions.

Human Tendency to blame someone else :D

But It has made my comp slow.
It is now taking more time to boot.

Reduce the Default 30 second Timeout to 2 sec and your BOOT Process will be fast LMAO :D

Yeah, boot-time will increase. But once loaded, an OS won't be slow, unless you are not using any virtualisation technology.

lol... :D
how to do that?

Not necessarily. A boot loader takes time to read the MBR. So, even if that delay is reduced, the boot time will be longer than that of a single boot.
lol...
how to do that?
If you're on GNU/Linux, edit GRUB.conf in /boot/ and reduce the timeout delay from there.

LOL, someone lacks on Funny bone :D no offence :)

MBR is only a few bytes bro, dont expect ages to read MBR

I think GRUB bootloader for GNU/Linux etc will be having a default 30 sec delay to choose which OS u want to run.just select the OS of ur choice and run.that's it.nothing to blame.just look carefully at GRUB screen.
or u can even hide grub to boot directly a os(need to edit /boot/grub/menu.list and add hiddenmenu and select a default os by number).

yeah it makes the booting slow ... i agree ... i take a lot of time to decide which OS to boot into :D

I use XOSL as my boot loader. Simple, fast and easy :)

But why will the boot time increase (without considering the time to choose the os)?

If you don't consider the time of choosing the OS, then boot time doesn't increase. It remains the same. It's only upto selecting which OS to boot that extra time is taken.

No use of any third party software to configure boot system.Just follow this:

Start--> right click my computer--> properties-->Advance-->startup and recovery-->setting.

Now configure as per ur choise.

Tell me how to reduce it I am Using WinXP and Vista
Vishal Gupta
May 8, 2007 at 9:08 PM
^^
There will be 2 boot loaders: one of Vista and one of XP.
U'll hv to decrease time-outs of both boot-loaders. So just do following in both OS:

Open "sysdm.cpl" and goto "Advanced" tab and click on "Settings" button in "Startup and Recovery" section. Now u can decrease the time of "Time to display list of operating systems".

U can also do the same by using "msconfig". ;)
