Seriously?! _______________________________________________

Actually, my redhat version is an old one that does not recognize usb disk (but my centos can). So I thought if I can install redhat on one of my centos partitions and then copy its contents to usb disk via 'dd if of' utility.Can you please let me know how can I install redhat on my centos?

Just learn to do some amount of research on your own so we don't feel you are just using the list to do your work for you.

Google is a wonderful resource, and quite frankly, would have presented you with *thousands* of applicable hints for every issue you've raised here. The CentOS web site and wiki are also great resources; as are the documents in /usr/share/doc/* and the man pages.

If we saw you expending some effort to solve your problems before coming here we wouldn't mind assisting you.

Please point out the search result that will solve his problem if it is so easy for you...  Or if you can't, please avoid polluting future searches with non-answers.

Specifically, he needs a search result that shows how to get the older RedHat installed on the USB disk it doesn't recognize.  There might be a lot that show how to point a grub entry to different boot partitions, but he won't get that far.  And if he copies a working image from a different install it still probably won't recognize the disk it is on, and even if the hardware drivers are there he would have to rebuild the initrd to contain them (and what's the driver name???).

My advice is to buy hardware that an OS recognizes if you want to actually use it.  And if you just want to try it out (doing research, perhaps?), install VMware on the best machine you have and run the OS in question as a guest.  In many cases you can find an image already installed that you can just download and run under VMware player.  If you have to build your own, you'll probably want the latest version of vmware server 1.x that you can find (the 2.x versions have a problem running under Red Hat or Centos and  nobody likes the web based console).  Or if you can meet its hardware requirements, load ESXi on the bare machine and run all of your other OS's under it.   VMware presents virtual hardware that the guests will see as scsi or ide drives regardless of what the server is actually using and you can generally copy the images around to different physical hosts - and you can do what you need with the free versions.

Actually if he has a CPU with vmx/svm extensions I would have suggested imaging the old redhat disk to a partition (or file) and using a kvm instance to run it with emulated ide and nic .... but quite frankly after seeing his noise on here for so long (and now at the ubuntu-users mailing list... oh yay?!) with not even the least amount of research I'd rather he just unsubscribed and stopped pestering with any task he needs to do at work/home/school.

Inevitably some troll will probably point out or lack of assistance and sarcasm in this case as that unfriendly FOSS community that yells "RTFM N00b!" in some slashdot discussion in future... but will just have to archive his more inane requests for defence then ;)

If he doesn't have a CPU with vmx/svm extensions I'll just quietly giggle in the corner at the concept of booting an OS that doesn't recognise USB-storage (which kernel was that introduced again?!) off a USB storage device...

Hadi's emails go straight to trash for me but I see responses to his queries. He regularly posts similar questions to three lists to which I subscribe:

http://lists.centos.org/pipermail/centos/2010-August/097561.html On my centos machine, I need to install redhat on one of its partitions and so make it dual boot. Can you please let me know how this can be accomplished?

http://lists.debian.org/debian-user/2010/08/msg00106.html On my debian machine, I need to install redhat on one of its partitions and so make it dual boot. Can you please let me know how this can be accomplished?

https://lists.ubuntu.com/archives/ubuntu-users/2010-August/224844.html On my ubuntu machine, I need to install redhat on one of its partitions and so make it dual boot. Can you please let me know how this can be accomplished?

--- Wow determined to get an answer! I give him that. How many more?

Just to point out though, that the first query did seem like an elementary one that could have easily been solved--the onus, in this case, is probably on the OP, but at any rate....

VMware on the best machine you have and run the OS in question as a guest. In many cases you can find an image already installed that you can just download and run under VMware player. If you have to build your own, you'll probably want the latest version of vmware server 1.x that you can find (the 2.x versions have a problem running under Red Hat or Centos and nobody likes the web based console).

Aha---have you tried the latest VMwareplayer? It seems to be their replacement for the old VMwareserver. It now enables you to install an O/S, so these days, I'm recommending it over VMware server--like you (and most people), I greatly dislike the 2.x way of doing things.

There is also the lighter, and at this point, probably less feature-ful VirtualBox, of course. However, VMwareplayer, like the old VMware server (that is, 1.x) allows you to install a wide variety of systems.

Also, as was said above, you can often find a prebuilt image.

VirtualBox works ... until it doesn't. Quality control, in my experience (it would really take a survey of hundreds of users to be sure, since everything has bugs _someone_ will encounter), has slipped considerably under Oracle management.

Can't speak to the relative feature-fulness of VB. Might depend on whether you count simplicity as a feature. It is pretty darn simple. So for someone needing a simple answer....

Yes, exactly--that's its main benefit I think. For casual testing, for things like running a client to quickly test ldap, that sort of thing, I find it quite handy.

I haven't done any benchmarks in a long time, save for an almost useless one, compiling FreeBSD make buildworld--VBox was about an hour slower than VMware-player, and KVM-qemu was faster by about 10 minutes--that is, faster than VMware.

So, my REALLY subjective impression is that KVM-qemu (on a supported CPU) is somewhat faster than VMWare-player--the new one--which is faster than VirtualBox. VMware-player and VirtualBox are probably about equal in ease of use, VBox is smaller, possibly a bit faster to set up.

Going to re-title this one post as it had nothing to do with the OP's question.

Please quote the part where I said it was easy if you'd be so kind? I can't seem to locate it on my own. No one ever said things were going to be easy in this industry; if they were then many of us would be out of a job :) But that's really not the point of my post as you really should be aware of, Les.

Specifically, he needs a search result that shows how to get the older RedHat installed on the USB disk it doesn't recognize. There might be a lot that show how to point a grub entry to different boot partitions, but he won't get that far. And if he copies a working image from a different install it still probably won't recognize the disk it is on, and even if the hardware drivers are there he would have to rebuild the initrd to contain them (and what's the driver name???).

I am fully aware of all this. And I also am aware that you know of the back-history of Hadi's blatent misuse of this list.

I, and quite a few others I might point out, are well aware of Hadi's use of this list to solve all his problems without doing any research beforehand. If it was only on occasion it would not be a big deal; however it's not a rare event here.

So, yes, I maintain that google, and the other resources I mentioned should be his first line of help when issues he's not versed in arise.

Excuse me if this doesn't add an air of spoonfeeding. I am all for helping people. I am not, however, all for being used.

If you'd like to continue this thread then I ask you, as a benefit to this list, that you do so privately to the address above. Thank you.

And just what was that point?  If you don't have an answer, why is your post any less an abuse of the list (and future searches) than the question?

Sometimes people feel enough is enough? Something or someone is so irritating over such a period of time you just can't stop yourself saying - what you again?! Please just go!

And as for that point about an AI doing this over multiple lists that might explain a lot.... especially the question that is essentially a repeat of the previous ones or contradictory to previous requests for help... hmm maybe whoever is controlling this AI is trying to generate a giant FAQ for any distro.....
