Will dual boot hurt performance?

English Install/Boot/Login
#1

I am getting very very comfortable with OpenSuse, however, there are still appilcations here and there they i DEPEND on Windows.

I want to know the benefits of a dualboot.
I want to do this untill I can fully move to SuSe

Here are some questions that I have

  1. Will the dualboot, hence rezising my Windows partition hurt its performance?

  2. How can I uninstall suse and go back to just windows?

Thanks in advance

If you want to have zero impact on Windows, I would suggest installing Linux on an additional disk, and using the Windows bootloader to chain to the Linux bootloader on its disk.

Will dual-boot hurt performance? No, it shouldn’t. How to go back to
windows (meaning prevent any booting to Linux)? Either set windows to
be the default boot option or do a windows repair install which will
overwrite the boot loader and prevent Linux from loading at all until
you undo windows’ “repair’s” damage.

Good luck.

How would i do that?

I have a 200GB HDD i want 100 and 100 it should be enough right?

Read swerdna’s writings on bootloading (look up swerdna in this forum).

Buy a second disk and connect it up.

(One problem with shrinking NTFS to install Linux is that when you want to put things back the way they were you have to use something like ntfsresize (available on the systemrescuecd live CD and probably other places), and NTFS resizing, indeed any kind of partition resizing, involves some risk, so you should back up your data first. If you install on a new disk, there is no such risk. But of course it will cost you more and consume a bit more power.)

I will just install on the same HDD… i will basically just use windows for gaming and oper specific apps… :slight_smile:

Just a caution
If you shrink a windows NTFS partition:
If it’s vista, only shrink it from inside the running vista operating system. The Linux apps for shrinking NTFS haven’t caught up with the new version of NTFS that was released in vista.
If it’s 2000/XP/2003 then it’s OK to use a Linux application like GParted (or even Yast) to shrink it.

It’s OK to put Linux on disk #2 with windows on disk #1, except it’s a bit tricky if the second HDD is a portable (usb) HDD. I’m a bit confused by your posts. So if you’re looking for pitfalls to avoid, say whether you will be putting Linux on the first internal HDD, on a second internal HDD or on an external portable HDD.

And I’m not sure what you mean by “I have a 200GB HDD i want 100 and 100”.

First of all, i want to THANK YOU for taking time into explaining all this.

I wont give up, and I really want to “establish” myself on SuSe.

I have reinstalled like 4 times, becuase I am one of those noobs like thinks is not a noob and I endup breaking my system.

I have 2hdd, one with windows and one with all my songs, videos etc.

i WANT to install suse on the same HDD as windows and make it dual boot.

I guess that is the safest way right?

Windows and Suse will work perfectly?

Now that being said what do you suggest i do?

#9

If you are not running Vista

Open Windows
Disk Clean
Disk Defragment
Restart
F2 or whatever to change to booting from a CD/DVD
Accept openSUSE’s suggested partitioning
Answer all the other questions, particularly the one about whether you want to have the same password for root and first user with care.
When asked to restart, F2 or whatever to change to booting from the HDD.

If you are running Vista, get it to do the partitioning and select Expert mode when you get to partitioning. Before you leave Expert mode, make sure you have mounted your Vista partition.

So in addition to the good advice of john_hudson, a few things:

I think it is.

Windows and Suse will work perfectly?

If all goes well

Now that being said what do you suggest i do?

I think the first thing to do is plan and prepare the partitioning rather than just blindly accepting Suse’s suggestions. So, since you’re going to use sda1, the first internal hard drive, let me ask about it:

  • What size is it?
  • How many partitions are on it (maybe just one, whatever) and what file systems are they (e.g. are they fat, ntfs, Linux ext3, swap, whatever)?
  • Which partition is the windows operating system and what is it (2000 or xp or vista?)?
  • How much space will you be using for the total Suse enterprise?

Maybe from that I could make some suggestions.
