Help me!


Hi members,

I am new to linux and was trying to start by installing rhel 7.2 in my laptop, currently running windows 7,from a usb media.I downloaded a rhel 7 dvd iso image and converted it into a bootable image by iso2usb.

I then changed the boot priority settings in BIOS to external device(didn't have any option for USB) and restarted my laptop with the USB. I was successful to a point where I could see a GRUB screen.

However, while installing rhel 7.2, I got stuck with the following error:-

[ 193.845250] dracut-initqueue[779]: Warning: dracut-initqueue timeout - starting timeout scripts
[...]
[ 198.557262] dracut-initqueue[779]: Warning: dracut-initqueue timeout - starting timeout scripts
[ 198.557679] dracut-initqueue[779]: Warning: Could not boot.
[ 200.161146] dracut-initqueue[779]: Warning: /dev/root does not exist
[ 200.170895] systemd[1]: Starting Dracut Emergency Shell...


Warning: /dev/root does not exist

Generating "/run/initramfs/rdsosreport.txt"

Entering emergency mode
Type "journactl" to view system logs
You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot after mounting them and attach it to a bug report.


I did a blkid and noticed that the device LABEL of the USB doesn't match with the USB name.

Can somebody suggest how do I change the LABEL to the correct USB name?

Thanks in advance!

looks like your conversion has failed. Or the image was not suitable to use it on usb. Or something else. But you can ask redhat support ...
Or, if you have not bought any subscription better to try centos.

Aside from what pan64 said, there's a few things here that are obvious questions:
  • You said you did a blkid...why?
  • Did you look at the rdsosreport.txt as generated?
  • Did you look at the system logs??
  • Best question: ***WHY*** are you loading RHEL 7.x on a laptop???
You say you're a new user, so you may not be aware that RHEL is designed for SERVERS, not consumer hardware. Support for things like wifi/sound/bluetooth, or even basic GRAPHICS may be spotty and/or impossible. Also, RHEL is NOT FREE...loading it without a valid subscription is possible, as is using it. But you won't get the online repositories, you won't be able to load software/update things, and the only real thing this gets you is an unstable, unpatched, insecure system. CentOS is better if you're not going to pay, and it's 99.xx% identical to RHEL, but totally free.

And again, WHY a server-class distro? What's the point? If you're learning, ANY version of Linux is about the same, aside from some distro-specific things. You could (and SHOULD) load Fedora if you want to stay in the RHEL ecosystem. It IS designed to support a wide range of consumer hardware, and will probably 'just work' better out of the box. And the first two hits in Google for "how to load fedora from usb" are:

Thankyou for replying to my post!

Yes,I am aware that RHEL is an enterprise server OS.Can’t I install it on my laptop? Dies RHEL have any server hardware requirements? I wanted to install RHEL in my laptop and then install a server application on it.

I think it makes more sense for me to install CentOS as I don’t want to buy any subscription.Thankyou for the suggestion!

Yes, I did check the system logs which showed the same dracut error message as in the console(which I had pasted in my last post already)

I couldn’t do a ‘cat /var/log/messages’ as the system was on emergency mode and it won’t recognise the command ‘cat’.

I did a ‘blkid’ to check the USB label as I saw somewhere(in google) that dracut error comes when the name of the USB doesn’t match with the device name the kernel recognises.

This is the link which I followed before doing a ‘blkid’.

I don't know what server application do you want to use, but that should work on CentOS (or ubuntu, debian, whatever) too (in general). If there were no special requirements/dependencies.

Go back and re-read my post. What you **CAN** do is different that what you **SHOULD** do. You CAN drive a dump truck to and from work every day...but would probably be better to get a car instead, wouldn't it??? While it may load, the things that I mentioned may not work well/at all.

Yes, and they're listed on the Red Hat website

Again, you DO NOT NEED RHEL or CentOS to load a 'server application'. What is this application? Pretty much ANY distro of Linux can easily run 99% of applications, from web servers, DHCP, DNS, etc.

No, it does not. **AGAIN**, CentOS/RHEL/SLES are DESIGNED FOR SERVERS....NOT LAPTOPS. Your mouse/touchpad, sound, bluetooth, wifi, etc., may not work AT ALL, and if they can be made to work, it won't be easy. AGAIN, server distros are designed for servers...they run in back rooms, and typically don't have any consumer hardware on them, and most of the time they don't even have screens.

Again, you're missing something. You were asked if you looked at the .txt file mentioned. Did you??

You say you're a new user to Linux, and you have two experienced users telling you to NOT use CentOS/RHEL, and to load your application on another distro like Fedora or Ubuntu, but you're ignoring this advice.

Quite a mouthful, TBOne.

@OP, don't try to jump too much. Anyway, things you learn at client OSes such as Fedora will not go wasted if you have to apply the knowledge in Server OSes. In fact, it will help when things go wrong you will be able to determine whether it's client side issue or server side problem.

Basic step is very important. Cheers!

Getting into a new OS can be a little daunting for many. RHEL is certainly not the best way to go, but it can be done if you are willing to roll your sleeves up and do some troubleshooting. That being said and as pointed out, you do have to pay to use RHEL. If you are trying to find a distro that is similar, CentOS is good but you can also look at Fedora as it has a workstation component.

My advice with any OS is to start on the client side and get it under your belt and then when you get comfortable, dig deeper.

I, like the above posters, suggest installing Fedora instead of CentOS or RHEL. RHEL is for enterprise servers, like they said, it's not for laptops, it's for server rooms. Fedora is basically RHEL for end users. I work for a large corporation that has over half of it's server farms running RHEL. I took a course to become RHEL certified and would not run RHEL on my own computer, unless I had a test machine and was doing it only for studying for the test. I have ran Fedora on my computers for years to help keep consistency between what I did at home and what I could do at work. Even at work, I installed Fedora on my workstation. So if you are wanting to run RHEL so that you can use the knowledge at work, then install Fedora instead, you'll still learn lots of useful information. However, if you don't need to apply it to work, you just want a great OS at home, a good distro to use would be MINT. It really just works right out of the box and is based on Ubuntu so almost all Linux software is readily available and packaged to use without any user intervention.

I'm not sure why people still aren't aware of the developer support offerings from RHEL. They were launched back in 2016. It allows folks, such as yourself, to sign up for a free developer account which not only allows you to run RHEL free of charge (no phone/email support), you also have access to the access.redhat.com knowledgebase and a few other perks. Here's more details:
https://developers.redhat.com/products/rhel/download/

OP: if you're shooting for "path of least resistance", it might be better to find a distribution of Linux that supports the particular chipsets found on your laptop. You can Google search which model of laptop for which distribution of Linux will be most compatible. Between the various distribution forums and this site, there's vast amounts of knowledge at your fingertips that can help solidify the choice for what might work best. Leverage that information to your benefit. Depending on your laptops "beefiness", e.g. CPU cores, RAM, etc., you may be better served by standing up a Linux distro you wish to learn more about as a virtual machine within Virtualbox. Run something like Ubuntu, Fedora, Linux Mint, etc., on your laptop natively, then install Virtualbox to serve out virtual machines for testing. I believe this might be the most efficient approach if the laptop has sufficient specs to support the VM(s).

We are well aware of it, thanks. You can ALWAYS run RHEL free of charge...what you don't get is access to the Red Hat network if you do so. The developer option gives you limited access...but neither of these things matter. RHEL is **NOT** designed for laptops, and certainly isn't designed for new users. And the OP clearly stated he was a new user, and was trying to load this on a laptop. While you may get things working (sound/graphics/whatever), it may not be easy or at all possible with RHEL. And The RHEL developer edition requires sign-ups, etc., etc., while CentOS does not, and is almost totally identical to the 'real' RHEL. So what's the advantage of RHEL Developer??

...which is what the OP was told several times already (posts 3, 6, 7, 8, and 9) to use a different distro, with Fedora, Ubuntu, and CentOS all mentioned.

What, exactly, is the problem here???? You've taken this attitude with several people in the past, for no apparent reason.

If you don't like coming here, then don't.

That's just it. You seem to assume some sort of attitude when there is none. I'm simply trying to help the OP and folks such as yourself just seem to automatically assume malice. I don't know why you react the way you do, but it turns people off from trying to help. Want RHEL? You can get RHEL. Pretty simple.
