PXE Won't Boot

A week ago, I realized that I could not boot live disks. At first, I thought that it was the optical drive not writing the disks correctly, but when I tried two live disks that I've used many times before nothing happened with those either.

I have CD/DVD drive listed first in my BIOS' boot order and I even tried selecting the optical drive in the menu when the computer started and it still does not boot a disk. Thankfully, my somewhat old hard drives are still chugging along but I need to be able to use a live disk, in case one or both die on me.

My question is, how can I know for sure what the problem is? Is there a way to test the optical drive (Samsung Super Writemaster - which has a bad rep)? Could it be my motherboard. It was bought new 2 years ago, and there are no other issues with it. Also, I have been able to create playable DVDs on my computer with the Optical drive that work perfectly on my Bluray player, yet I cannot play the movies or open a data disk in file manager on my computer. What does that mean?

I want to know that it's worth it to buy another burner, before shelling out the money when I'm already practically broke from Christmas gift purchases. Any suggestions on how to test the optical drive would be appreciated.

Booting to CentOS Linux problem. I have an HP desktop PC with an AMD CPU and win8.1 installed on it with UEFI as the boot process. The CentOS7 DVD indicates that I have installed the CentOS successfully. When I boot the PC it does take me to a menu offering CentOS and Win8. Win 8 will boot correctly. However, when I try to boot to CentOS I get a screen that says “Kernel not found”. The boot loading process continues until it ultimately brings up a terminal login screen. When I try to login with my password and usr name it tells me that they are wrong. I suspect the Kernel not found is the real problem but I can't get into the CentOS program to see if GRUB or any of the other programs are missing or defective. So far I have not disabled the UEFI since I didn't think I needed to. Any suggestions?

I have several computers connected to a D-Link DIR605L router, two with ethernet cables and two through wifi. The Windows XP computer can see itself and nobody else. The Ubuntu (trusty) desktop and Ubuntu (lucid) netbook computers see nobody (unable to retrieve file list from server) and the Windows Vista computer only sees itself. Clearly, I have failed to configure something or a set of somethings.
Do I have to have one of the computers always on, acting as some kind of file server or can the router do this job? This is a new router. My old one (whose power supply went phut) connected everybody without arguing about it and we could share files around, even with a mix of OSs.
Since this is a local network only, I have no firewalls enabled, as far as I know ...
All of the network set-up posts I've found rabbit on about how to get your internet connection working through your router, which is not an option for me. I have dial-up working on the XP computer and a mobile wireless USB dongle for internet access on the trusty desktop.
I've installed samba and a few other packages, but so far, none of them have solved my problem. Can someone please tell me where to start and which tutorials to read? If I have to set up a computer as a file server, I guess it will have to be the XP thing, as it's the only one that is always running, but I'd like to avoid that, if possible, as I speak XP worse than I speak Ubuntu.
BTW, D-Link are no help at all, two hours on the 'phone and they were still trying to get me to connect to an ADSL service I don't have ...

Hi Folks,
Installed Mint-mate 17.
It gives message:You are now disconnected" after logging in.
I restart, the network connection comes.
It is not "networking restart", but system restart.

Tried five more times. The behaviour is every time the same.
After booting the system, no network connection. But from there I restart the system, then network connection is on.

Very irritating to always boot it second time to get the network connection up.

The computer is a desktop Dell Optiplex 9010.
On the same computer, Windows 7 runs without any problem.

Any idea how to fix it?

Thanks

Hi

I am very suprised! I previously had a Windows 7 desktop, dual boot with Windows Server 2012 R2. I didn't care much about 2012 R2, so I went with a Debian server on another computer.

I wanted to triple boot my computer, so I looked at my BIOS to see if my computer has UEFI support, but it doesnt, so I am not able to boot to GPT. One decision lead to another, and I decided not to install Hackintosh. As part of this process, I had converted it to GPT, and then back to MBR when installing Windows 8.1 Pro. Everything went well.

When I went to install Debian 7, it was not recognizing anything on that drive. I found out it was a backup GUID partition table left over. I used fixparts found on rodsbooks.com, and I fixed the disk partition table.

Now this is where things get weird. Before installing, I created a primary partition for /, and an extended partition with 5 logical partitions inside it. I installed Debian 7 from a live install DVD, and I manually created the partitions. I created a 4GB /, 16GB /usr, 4GB /var, and 64GB /home. Then I left a bunch of free space (~145GB) and then 16GB swap space. (I have 8GB ram, and I plan to hibernate sometimes).

After a successful installation, installation of packages, reboots, and frustration with PCI card problems, I rebooted to Windows 8.1.

Upon opening diskpart gui, I was greeted with the picture attached.

WHAT IS GOING ON?

I'm not really a newbie, but thought that this question would fit best in here. I had the genius (not really) idea of installing GRUB2 onto my USB flash drive, then realized that it wasn't such a great idea after all. I reformatted the USB drive and after that my computer failed to boot when it was plugged in (presumably searching the drive for a bootloader that doesn't exist). It does not even get to the BIOS screen unless I unplug my USB.

Then, I tried doing
Code:

dd if=/dev/zero of=/dev/sdc bs=512 count=1

and I still have the same problem. I'm not really sure what to do at this point.

Any help would be greatly appreciated,
Thanks.

Hi all. I'm trying to set up a netbook with Ubuntu for my computer-challenged Mother. I downloaded the image file to the download section of the new netbook, created a USB stick to boot from and then restarted the computer, pressing F2 in order to change the boot order. Using the "+" key I was able to put [Removable Dev.] on top: "1st Boot Device", but, and here's the thing, it is disabled: "A devince enclosed in the parenthesis has been disab led in the corresponding type menu." I do not understand this, nor do I know what to do. Help please....

Hello

My harddrive on my home server computer seems to have corrupted, likly due to some recent power outtages (using it as a home nas, game server, nothing important really)...
It was previously running windows 7 because I took the harddrive from my old computer, but now as I have to format it anyway I might as well do it right.

Since my server does not have a CD drive (that works) I am hoping for a way to intall Debian onto the harddrive from my main computer (running windows 8).
I have plugged it in, and the drive seems fully functional.

I'm not very skilled with Linux, and am completely on bare ground. My googling has not come up with an answer that I have understood yet.

TL;DR - How do i install Debian onto a secondary harddrive plugged into my computer take this drive and put it into another computer and boot from it?

I have a new PC and it's my first with a UEFI motherboard. I've been using Manjaro on it for a few weeks but now I want to switch distros. Before UEFI it was easy; I'd just tell the new distro's installer to overwrite / and use the existing /home as /home. But now I have these extra partitions that Manjaro created regarding UEFI and I'm not sure how to go about it.

I just used the Linux Mint USB live disc and launched the installer. The partitioning tool showed me /bios and /EFI in addition to the other partitions that are more familiar to me, like /boot, /, /home and /swap. It would not let me alter the /bios and /EFI partitions.

In order to preserve /home. what should I tell the Mint installer to do? Should I just overwrite /boot and / as I've always done? Will it work like that on a UEFI system? Many thanks in advance for all advice.

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.
