Dual boot advice


Hi,

I have a new laptop with Windows 7 installed. Is it true I can resise my HDD using Gpart without disturbing the MS os?

I would like to add Ubuntu and have a third partition to which both oses have access. Can you direct me towards any advice?

Thanks

Yes, it's true. Just be careful with Windows 7, I think I have read somewhere that setting up dual boot with it is not as easy as it used to be with previous Windows versions. Unfortunately, I cannot provide any guidance on that, I have never even touched Windows 7.

The third partition should be formatted with the FAT32 file system. NTFS is accessible from Linux, but you could run into problems by doing that. The ext2 file system is accessible from Windows, but it requires additional software and you could run into problems doing that. FAT32 is the only 100% safe, trouble-free choice.

Make absolutely damn sure you have all your data properly backed up before you even try anything, because messing with partitions is *always* dangerous, even if you know what you're doing. If you don't know what you're doing, it's suicide.

I heard that, too, through the grapevine. And if the partition manager of Windows (diskmgmt.msc) is able to resize the partition, you should rather use that instead of a third-party tool, though gparted can do it. But since NTFS is proprietary, you can't be sure if a third-party tool gets it all right.

I have, on several occasions, but I avoid it whenever I can.

Yes. Just bear in mind that FAT32 has one limitation: The maximum supported file size is 4GB. So if you have to deal with very large files (HDD or DVD images, virtual machines, large video files), FAT32 may be ruled out.

ACK. Can't say that often enough.

Thank you very much for that hint. I had no clue where in Windows 7 the disk management was hidden and were searching for that command desperately. Have to deal with this only when buying a new PC...

By the way: openSUSE did install very well together with windows 7. No problems so far. Only drawback was that windows was unable to free 800 GB of unused hard disk space because of some files it can not move -.-

It's always been that command since Window 2000. There is also a complicated way to get there via Control Panel, Computer Management, and then another two or three clicks, but I rather prefer calling the relevant configuration tool directly from the command line.

Wow, what's on that partition? Have you tried to defrag it before? That might help, though it's not guaranteed.

Not much but wasted space...

Yes, that was the way I used to take. But it seems to me, this is no longer available in seven, at least not in Home... Anyway, I don't care as long as diskmgmt.msc brings me to where I want.

Well basically space I could use for my file server to come. There is about 30 GB windows 7 and stuff that shipped with it and a lot of free space. Yes, I did a defrag before resizing, and as I was unhappy with the result I rebooted and did a second defrag. It is still not possible to make the partition smaller than 800 GB. Not fun, but reminds me why I left windows behind..

Use gparted to shrink the Win7 partition to whatever size you want. It can move what Windoze considers "unmovable". Win7 never seems to shrink to less than 50% in my experience.

Note my sigline.
