Emachines Et1331, Boot Problems, Missing Modules, /dev/disk/by-uuid/4b69e9df-e......

Hi

My machine was a dual boot debain + W7. The debian had LUKS encryption and LVM.

I had to re-install W7 and now there is no access to the grub menu and of course to the debian installation.

I tried "boot repair disk"
http://sourceforge.net/projects/boot-repair-cd/
, but it couldnt access the encrypted volume. It did generate the following output:
paste.ubuntu.com/10591353

Would appreciate help how to get the boot repair disk to access the encrypted partition and recover the grub menu

Thanks

Hey,

My plan is to run some Linux distro's on an external USB HDD. So far I have been able to instal elementary OS, it thus far boots with the elementary OS logo and hangs for a while when it gives me the following message:


"Gave up waiting for boot device.
- Boot args (cat /proc/cmdline)
- Check root delay (Waiting long enough?)
- Check root (Waiting for the right device?)
- Missing modules (cat /proc/modules; 1s/dev)

ALERT! /dev/disk-uuid/*super long number* does not exist. Dropping to a shell!

BusyBox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) build-in shell (ash)

Enter 'help' for a list of build-in commands."


To give you an idea of the external HDD partition:
60 GB: ext4 (elementary OS)
4GB: SWAP
Free Space
80 GB: NTFS (Random files)

The ext4 was given '/' for mounting point to keep it simple for now. The 'boot part' I've set to instal on sdc. Which is the external HDD. (I wasn't sure whether I should have chosen the ext4 partition or not.)

Please let me know if you need any addition information. I hope someone is familiar with the problem or knows a solution.

Thanks in advance.

Friends,

I'm completely a Linux newbie, so explain as much as possible.

I installed Linux Deepin on dual boot(practically, triple-boot).
When I select the Linux Deepin option in bootloader, I mostly get a blank screen for a long time.
After practically 2 mins, it presents with some lines of text which I, being a newbie to Linux can't comprehend and hence, cannot counter the error.
The lines go:
"
udevadm settle - timeout of 30 seconds reached, the event queue contains:
/sys/devices/pci0000:00:1d.7/usb1(1080)
/sys/devices/pci0000:00:1d.7/usb1.1-0:1-0(1081)
up waiting for root device. Common reasons for this problem:
root args(cat /proc/cmdline)
Check rootdelay = ...[There's something here I cannot recollect at the moment]
Missing modules(cat /proc/modules; ls /dev)

ALERT! /dev/disk/by-uuid/b4b672ea-c6e5-47fe-a174-165ffde63c8 doesn't exist!
Dropped to shell!
"

Then it goes to a Ubuntu shell or something of that sort.


Surprisingly, every-time I boot into Windows and then restart my desktop and then boot to Deepin, it successfully boots in.
I have Deepin installed on external hard disk which is not very fast(just mentioned this if it is of any use.) Also, my Windows is extremely slow in booting up, it takes almost 10 mins, which is why I switched to Deepin, which boots up almost in 2 mins if it does.

Any help would be extremely appreciated.

lsmod is command to list loaded modules and I referred man page of lsmod that shows it refers to /proc/modules file. In terms of my os platform, Ubuntu, almost available modules are in /lib/module directory. I think OS kernel naturally loads modules in there. So, What does kernel refer to load modules at boot time?

Is there any files to be refereed for loading or mechanism can't know easily for end user?

I recently purchased a laptop that came with Windows 8.1 as the OS. I am trying to switch it over to Linux Mint 17.1 (Rebecca). I found an Ubuntu disk loader that I placed on a DVD and it boots just fine. Downloaded the 32-bit Linux Mint .I so and burned it to a DVD. Tried to boot from it and nothing. Being new, the problem pretty much has to be something insanely simple but I sure can't find it. Would really appreciate any expertise out there.

I am having problems with my Sony Vaio windows
it boots up saying (on a black screen, grey text):
==============================================
Windows Boot Manager
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."
If you do not have this disc, contact your system administrator or computer manufacturer for assistance.
Status: 0xc0000225
Info: The boot selection failed because a required device is inaccessible.
Enter=Continue ESC=Exit
==========================================
No matter how many times i tried to restart and even tried F10 repeatedly or Alt-F10 I can't get to any other screen other than the above screen.

So I thought ah to hell with windows on this machine. I'll just install a linux distro because it's for my uncle all he really needs is internet and watch youtube videos/movies.

I have successfully burned and installed Fedora before on other machines using LiveCDs when they had CDs.

This time I tried to burn the DVD since it's it doesn't fit on the CD (I got my ISO from http://download.fedoraproject.org/pu...86_64-21-5.iso)
But when i inserted my DVD and restarted the same black screen appears.

So i have been looking for an older version of Fedora that fits on a CD (I am thinking maybe it'll boot from a CD, not sure though) but can't find any.

Any thoughts or solution to my problem?

Thanks in advance.

Hi,

I have problems mounting my second drive at boot automatically.
(sorry i am a noob)

When i use the mount command, it works fine.
Code:

mount -t ext3 /dev/sdb2 /mnt/HD/HD_b2

But when i try to add one if the following lines to /etc/fstab
It will not mount the drive at boot or with Code:

mount -a

, also fstab is empty afer reboot (normal??)

Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 defaults,errors=remount-ro 0 1

Code:

UUID=553afede-fa45-4cdc-9972-c0a9aa899509 /mnt/HD/HD_b2 ext3 errors=remount-ro 0 1

Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 rw 0 0

Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 defaults 0 1

output blkid:

Code:

/dev/sdb4: UUID="bf594be6-ffb6-469d-a3a8-246be66a4d90" TYPE="ext2"

/etc/mtab:

Code:

sysfs /mnt/HD/HD_a2/squeeze/sys sysfs rw,relatime 0 0
proc /mnt/HD/HD_a2/squeeze/proc proc rw,relatime 0 0

When mount command is used Code:

mount -t ext3 /dev/sdb2 /mnt/HD/HD_b2

The following line is added to mstab -->
Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 rw 0 0

I diont know what i am doing wrong, mount for HD_a2 works fine (other disk, worked at default), i hav e NAS DNS-325 where i installed Debian on. I used this tutorial to install debian.

The strange thing is, i had to reinstall my NAS, and befor it worked fine after i had installed debian 2 years ago, i just dont remeber how i fixed this.

I just cloned a Centos7 "everything install" VM to a physical disk using VMWare Workstation and Clonezilla using the instructions he https://www.howtoforge.com/convertin...cal-machine-p2

Now, when the clone (physical disk) boots up, it drops into the command line with this:

Quote:
dracut-initqueue[417]: Warning: Could not boot.
dracut-initqueue[417]: Warning: /dev/disk/by-uuid/4b8b5627-9027-46f7-b722-61d3ddd28e74 does not exist Starting dracut emergency shell...
What I've tried:
1. I checked /etc/fstab and the proper UUIDs are there, including the one above.
2. Tried booting via USB stick installer into rescue mode, chroot /mnt/sysimage , and:

Quote:
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-oh_crud.img
and then
Quote:
dracut /boot/initramfs-$(uname -r).img $(uname -r)
...but I get this:

Quote:
cat: write error: Broken pipe
When I enter "blkid", I see the HD in question showing up as both /dev/block... and /dev/sdb... I tried "lshw -class disk" but it says "command not found". Finally, the rescue shell says it is mounting my disk in /mnt/sysimage and all my files are where they should be, so it appears it is seeing and mounting the HD.

Any suggestions? I am a n00b, so going off a lot of google and not a lot of understanding here.

I have setup a dual boot system with Fedora 21 and Arch Linux. The problem is that Fedora doesn't see my encrypted Arch installation. The installations are on separate partitions and do not share anything apart from hard disk space. I have run the following commands as root in Fedora:

Code:

grub2-install /dev/sda

Code:

os-prober

Code:

grub2-mkconfig -o /boot/grub2/grub.cfg

When I rebooted, Fedora was the only OS entry showing in the GRUB menu.

There was a suggestion from one of the members of the Arch forums that I should write the entry myself into /etc/grub.d/40_custom and then re-build the grub configuration or take the Arch entry from Arch's /boot/grub/grub.cfg and just paste it into the 40_custom in Fedora and rebuild.

How do I boot from a live Arch USB stick into the installed Arch and do as stated above? How would it work? Thanks in advance for your replies.

Hello,
the "lsmod" give the list of the loaded modules/drivers.
How to know when was theier loading time (start/end) ?
Is there any existing log file where that information can be seen ?
For another topic, see http://www.linuxquestions.org/questi...ml#post5362257, I am thinking the unfinished loading of a specific module (ehci-pci or other pci driver) or the loading of a module before another one, could disturb the loading of a module e1000e during a cold boot.
Thanks a lot for any help.
