   hi finid

   here are good hints for ssds… you get no better help as on
   http://www.anandtech.com/tag/storage ! i have 2 intel x25-m g2, expensive but very robust and fast and no problem with linux (http://www.anandtech.com/show/2614/12). at the moment i would probably take an ocz vertex 3. #! for example is started within a few seconds.

   hi finid

   thanks. it should work like this

   for my better understanding. if i would install it the other way, an grub1 distribution (pclinuxos or #! or pardus – the new review!) with grub1 in mbr over the already installed grub2 of lm, what would happen and how to modify the new grub1 in sdb?

   you can`t compare a normal hd with ssd. it is really fast, felt more than a couple of times faster. linux with ext4 is no problem. trim can be done in linux, but i not able to do it at the moment.

   hi finid

   thanks very much for your helpful tips… it should be no problem to use gparted for partitioning and make “sudo grub-install `(hd1)` inside lm.

   my actual configuration is:
   sda: sda1 (system reserved), sda2 (win7) – win-bootloader on sda
   sdb: sdb1 (/opensuse), sdb5 (home), sdb6 (swap), sdb7 (lm /), sdb8 (home) – grub2-bootloader on sdb
   both ssds are totally separated. at the start up of the computer i decide which hd to boot.

   my intention is getting independent of ms… i try my very best…

   my only question is: should the bootloader of pclinuxos installed on sdb1 or should i install no grub1 of pclinuxos?

     PCLinuxOS GRUB on sdb1. GRUB has to be installed somewhere or I do not know how the system will boot. Perhaps it will, but I’ve not tried that experiment.

     What type of performance are you getting on those ssds?

   Hi finid

   thanks for your answer. LM is already installed the way you wrote (sdb7,8) and openSUSE is at sdb1 (root) and adb5 (home), which I installed a long time ago. Everything is booted via LM GRUB2 without any difficulties, especially after the LM installation after openSUSE.

   I now would like to exchange openSUSE for PCLinuxOS or better Cruchbang on sdb1 and 5. Both distributions use GRUB1 and thats the problem. The main thing is that the new GRUB should recognize and boot both distributions and GRUB1 or GRUB2 is not so important. How to install lets say Crunchbang and especially the GRUB.

   Thanks for your help.

     This shouldn’t be a problem, but you have to be careful.

     You can install PCLinuxOS over OpenSUSE, but that, of course, requires manual disk setup. That is where you have to make sure that the LM partitions are not reformatted.

     After installing PCLinuxOS, boot into LM and reinstall GRUB with sudo grub-install ‘(hd1)’. Those, by the way, are single quotes.

     Out of curiosity, what do you have on sda?

     I’m going to recreate your setup in a VM, so I can test this for myself.

     You have not made any reference to sda.

     What OS or distro is on it, and how it that OS’ boot loader interfacing with what you have on sdb?

   So you wish to dual-boot with LM first and its GRUB in the MBR. From your description, the partitioning scheme should look something like this:

   sdb1 – PCLinuxOS /

   sdb5 – PCLinuxOS /home

   sdb6 – LM Swap

   sdb7 – LM /

   sdb8 – LM /home

   This scheme does not match wanting to install LM first. You get this type of scheme if LM is installed last. If you want to continue with the way you described it, you just make things unnecessarily difficult, and it makes my head spin just trying to imagine it.

   A question:

   When you boot the computer, what do you want to see, LM’s boot loader, or PClinuxOS’?

   If you can tell me that, I will be able to suggest a better method of doing it because what you described is extremely difficult to imagine.

   And the same problem is with a dualboot with LM (/ sdb7, home sdb8) and #! (/ adb1, home sdb5) with grub2 as bootloader, when #! is installed after LM. How can this be solved?
