UEFI Vs Debian - Cannot Boot Into Grub After Installation

UPDATED:
I installed a Deb 7 Srv w LVM w following partitions:
The end product should become a mail server (Citadel) and in time also a Web server.
Code:

Now i want to _shrink_ the HOME partition so I can expand my VAR partition. Looked for guides but haven't found any site useful so far

I tried to find a way to do it when I installed it but it didn't seem to offer me this at this time even I looked around for a while.

How do I do this shrinking of HOME and extending of VAR partition??
please be fairly specific as Im not a pro yet

I got this configuration.

When i type fdisk /dev/sda3 the system give me Unable to open /dev/sda3!

Could anyone tell me the solution?

As I'm sure there are other posts for this, I'm terrified to mess with disks in Linux as I'm very green. I've looked at one other post which suggests to run the following so I'm going to do the same. The drive provisioned originally had 400 gb, but currently has 500 gb allocated in vmware. Thanks so much in advance!

Everything is working great on this server, however I am seeing Disk doesn't contain a valid partition table. I have no issue reading and writing, this something that can be ignored?

I am trying to clone this machine to another server, both servers are Dell Poweredge 1900, with 3 – 250 WD drives (the only difference is the ‘B’ server has WD Cavier drives), pretty much identical machines, same processor and ram. I have a 2TB ext hard drive that I am using to store the output of DD. I have booted from the CD to a rescue system, then mounted my 2TB ext and did the following:
Code:

    # dd if=/dev/sda conv=sync,noerror bs=64k | gzip –c | split –a3 –b 2G –verbose - /mnt/exthd/

This gives me the following files on my external hard drive:
Code:

Notice sda is only 498.8GB where on server ’A’, it was 499.0. when I try to restore my files from the DD, I get an out of space error. To restore, I use the following:
Code:

    # cat /mnt/exthd/aa* | gunzip –c | dd of=/dev/sda
    
dd: writing to ‘/dev/sda’:  No space left on device
974127105+0 records in
974127104+0 records out
498753077248 bytes (499 GB) copied, 37067.3 s, 13.5MB/s

My guess, is that although the drives are the same capacity (3 – 250GB in RAID 5 array), the number of cylinders is different because it is a different model, and that is where it is running out of space, although I wouldn’t think it would.

Please correct me if I am wrong as I am a newbie, but if I do “# dd if=/dev/sda” that will take all the partitions with it? Such as sda1, sda2, sda3 correct?

My father passed away about 6 months ago and I'm just getting around to going threw all 18 hard drives... I have been using Ubuntu 14.04 for over a year now and while I'm not a pro I can handle most things.

One drive has LVM on it. I have attached it via a USB2.0 to SATA cable. I followed the instructions he http://linuxers.org/howto/how-mount-...rtitions-linux

So where did I go wrong?

Im experimenting. I loaded knoppix, my older version on cd used to work great but I suppose the 2005 cd just met its end of life. The machine Im on boots fine to Windows I just want to play around with Knoppix.

Anyway, I downloaded burned and loaded KNoppix 7.4. Im on it as I type.

That crusty old version of KNoppix .. I think 5.x era showed a hda1 or sda1 on the desktop. I could just navigate that through the windows files.

So I guess Im asking... how do I get the harddrive to show up in the gui .. or how do I unhide the drives ?

Did you find any way to get out with this error ? I've got the same with an extended partition...
Code:

# fdisk /dev/sda

I have an external disk connected to a raspberry pi to act as a nas, which I am accessing from a linux mint desktop machine.
The nas disk is 30GB, but according to my desktop machine, which connects through the file browser via samba, only around 318MB are reported as available.
If I try to copy a 400MB file it tells me there is insufficient space.
The disk is currently empty, so all 30GB should be available.

On the nas box, cfdisk seems to report the disk size and the partition size correctly:
Code:

                          cfdisk (util-linux 2.20.1)

I'm not sure where to look next.

Hello there,

I tried to install kali alongside windows and did it wrong probably. Now whenever I boot, grub loader sees only Kali and Free-DOS and doesn't see Windows.

I can still see the Windows partition in Kali and access the files however.
Searched online for a solution and saw that boot-repair could help me, however because some new update issue I cannot install it under Kali directly( see below link, it doesnt work for me).
askubuntu.com/questions/449818/cant-find-boot-repair-package-for-the-newest-version-of-ubuntu]

Long story short, I downloaded the iso version of boot-repair and tried to burn it onto a live-usb, but it doesn't load. All I get is a black screen with a terminal line running where I can't do anything.
I burned the iso using the terminal and the command below.
sudo dd bs=4M if=file.iso of=/dev/sdc
I burned the iso using unetbootin a couple of times and the same issue.


Any ideas? am I doing something wrong? How can I burn the iso disk to a live USB to run boot-repair? Or any other alternatives?

PS: first time linux user, I have no idea what am I doing so please be patient with me.
