Installed windows 10 on a new SSD but I apparently made the mistake of doing this while the original windows 10 HDD was still connected. Apparently the windows 10 installer edits the EFI of the original drive, which is definitely not wanted. Anyway, this causes the original windows 10 installation, on the original drive, to fail to boot because the EFI now points to a drive that doesn't exist. How can the EFI on the original drive be updated to correct this?
After messing around for a day or two I found out that none of the bootrec commands posted everywhere worked. For example:
bootrec /fixboot
The system cannot find the file specified.
The solution was to use "EasyUEFI" by "Hasleo Software" to edit the EFI to point to the actual windows installation. Took all of 2 seconds to fix after that.

Heyyy, it's my first time wanting to install Linux as my main operating system or something similar. I have worked with GNU bash commands before. First, I tried to install Ubuntu 22.04, but I got stuck on the "praping" (I think) Ubuntu drivers. I want to dual boot, as I have really important files on my main OS (Windows 10), and I don't want to lose these files. However, I don't know how to select a partition to keep the files safe.
I didn't try anything because I was afraid

Most likely a rather obvious question but nevertheless I am doubtful about it. For development purpose our team got an linux VM tot work on. Once in a while I met a lost+found directory. Most of the time it is not accessible (permission denied). What is the meaning of this directory. Has it been implemented by Linux or has it been manually by one of the administrators?
I do agree with #Arcturus-B and I put some effort in it to get some extra informatie. I found info at https://unix.stackexchange.com/questions/18154/what-is-the-purpose-of-the-lostfound-folder-in-linux-and-unix and http://www.linuxnix.com/2012/12/lostfound-directory-linuxunix.html I guess I was a little bit cautious and did expect to find so much detailed information about this.
Files that are being open when an unexpected shutdown occurs may be damaged. On the following power up, the fsck tool is run to try to recover them. If any file is to be recovered, it is placed in the lost+found directory of the partition the original was stored in.

Actually I am just trying to build up a cluster(beowulf) in which there is a modification required in /sbin/lilo for reflecting the access to master node by slave node after it goes up . I changed the /etc/lilo.conf.anaconda file for timeout=1200 , but unable to find the /sbin/lilo file to get result of added linux.Please help me that where do i verify that the modificaion is been implemented??....I am working on RHEL 4.
lilo was the boot loader of Linux a long time ago.
As far as I can tell, all distributions have moved to using grub as default instead, as it is much more robust. With lilo, the risk of ending up with a non-booting system were much higher.
It seems you are following an extremely outdated manual?

I have two USB devices which appear as /dev/ttyACMn (a barcode reader and a motor controller). For each of them, when I try to open them in the first 15 seconds after plugging in, I get a "device or resource busy" error. After more than 15 seconds, they open fine. Do you have any idea what's causing it?
I tried using lsof to check if a process is using the device, but it finds no such process (it finds my process after I manage to connect to the device).
I'm currently using Ubuntu 14.04, kernel 3.13.0 64-bit, but I have seen this behavior in earlier Ubuntu versions too.
Thank you very much,
Noam
I think the problem is ModemManager. It scans serial interfaces on startup to see, if they belong to a modem.

I recently made the following (i believe important) changes to my system
Actually I was following this tutorial to use something called Linux Containers.
So can you tell me if any of the following stuff is capable enough to crash my system ?
1. Making changes to /etc/fstab or
2. mount /cgroup which will try to mount cgroups automatically or
3 making changes to etc/network/interfaces or
4 making changes to /etc/resolv.conf
A typo in fstab can definitely make a system un-bootable. However, you should be able to boot from CD, mount the HD, and fix it.
