Recovery Image D Drive
Felicity
Not sure where to go from here. Can I recover the system from any of the hard drives? As one scenario I was thinking I would have at least two good hard drives that should be able to boot up as regular hard drives without raid but not sure how to do that. From there, I am hoping to image that system once it was able to boot and then rebuild the raid and restore the image.
The recovery image on my machine has been assigned to drive I need this letter for an external drive (to make it easy to move my Lightroom database between computers). How do I change this to another letter? This option is not available in Disk Management for drive D:. Will this prevent recovery?
Dell Technologies recommends that supported computers use Dell SupportAssist OS Recovery Automated by SupportAssist for a premium restoration experience. See our article, Restore your Computer Using SupportAssist OS Recovery for restoration instructions. For a list of computers that support SupportAssist OS Recovery, see the Dell SupportAssist OS Recovery Support Matrix.
If your computer does not support Dell SupportAssist OS Recovery, Dell provides operating system recovery images online. This is for the Windows, Ubuntu, or Linux image that was factory installed on your computer. The Dell OS Recovery Tool provides an interface to quickly download and create a bootable USB drive to reinstall the operating system.
The Dell OS Recovery Tool helps you download the operating system recovery image that is customized for your Dell computer and create a USB recovery media. The Dell OS Recovery Tool allows you to download either Microsoft Windows, Ubuntu, or Linux operating system recovery image that was preinstalled on your Dell computer.
Yes, the Advanced Mode in the Dell operating system Recovery Tool allows you to create a USB recovery media. It uses an operating system image file in ISO file format. This is useful if you downloaded the operating system recovery image using a Linux, Mac, or Android device.
Windows 10 or Windows 11 or Windows 11 recovery image enables you to format the hard drive and install a clean copy of Windows 10. The file size of this recovery image is considerably higher than the Windows 10 or Windows 11 Automated by SupportAssist.
The Windows 10 and Windows 11 Automated by SupportAssist recovery image can create USB recovery media for Dell computers that support SupportAssist OS Recovery. (Figure 12 [English only].)

Dell SupportAssist OS Recovery provides a recovery environment with tools to diagnose and troubleshoot issues that may occur before your computer boots to the operating system. When your computer is unable to boot to the operating system after repeated attempts, it automatically starts SupportAssist OS Recovery. This recovery environment enables you to diagnose hardware issues, repair your computer, back up your files, or restore your computer to its factory state.
SupportAssist OS Recovery is supported on select Dell computers that run a Dell factory-installed Microsoft Windows 10 operating system. For the list of computers where SupportAssist OS Recovery is available, see the Dell SupportAssist OS Recovery Support Matrix under Dell SupportAssist OS Recovery Support Documentation.
Typical recovery image files for the operating system in an ISO file format are between 5-16 GB in size. (The file size varies between different operating systems.) Once the file is downloaded, the Dell operating system Recovery Tool verifies the integrity of the file before creating the USB recovery media. The time to download and verify that the integrity of the file can vary depending on network speed and file size.
You may receive a "Not enough space on drive" error. Where you download a large file through a Dell online application such as Dell OS Recovery tool. This is due to a space limitation on the hard drive where the files are being saved to. Some operating system recovery images can be up to 16 GB in file size.
To correct this error, free up additional disk space on the hard drive. For information about freeing up disk space in Microsoft Windows, see the Dell knowledge base article: How to Free up Disk Space in Microsoft Windows.
The operating system recovery image may not contain the latest device drivers for your Dell computer. The latest device drivers are available at Dell.com/support/drivers. After the operating system is installed, Dell Technologies recommends that you download and install the latest device drivers.
The Dell operating system Recovery Tool fails to launch after installation, or running the installer does not start the installation process. You can temporarily disable the anti-virus or anti-malware software that may be installed on the computer and then run the application or the installer again.
If your device encounters severe issues, such as an inability to access the operating system, you can utilize a recovery drive to access the Windows Recovery Environment (WinRE). It assists in the restoration of Windows or the execution of system restore points. To use a recovery drive, you must first prepare an empty USB flash drive (with a minimum of 16GB of space) to create a Windows recovery drive. As Windows undergoes periodic updates to enhance security and device performance, it is recommended to periodically create a new recovery drive.
Note: When restoring the device via a recovery drive, the original disk partition data on the system drive may be deleted. (If your device supports MyASUS in WinRE or ASUS Recovery, functionalities built into the disk partitions on the system drive will be removed.) If you wish to preserve these functionalities, you can restore the device through a system image, thereby backing up the data in the disk partitions. Learn more about How to create and use Windows System Image to restore your device.
If you experience the device cannot boot, you can use the recovery drive to enter Windows Recovery Environment (WinRE), and then restore from a system restore point or reinstall Windows via the recovery drive.
I'm a new Linux user. I've reinstalled my Wubi from scratch at least ten times the last few weeks because while getting the system up and running (drivers, resolution, etc.) I've broken something (X, grub, unknowns) and I can't get it back to work. Especially for a newbie like me, it's easier (and much faster) to just reinstall the whole shebang than try to troubleshoot several layers of failed "fixing" attempts.
Coming from Windows, I expect that there is some "disk image" utility that I can run to make a snapshot of my Linux install (and of the boot partition!!) before I meddle with stuff. Then, after I've foobar'ed my machine, I would somehow restore my machine back to that working snapshot.
All references to the file system and hard disks are located locally on the virtual /dev/ filesystem. There are a multitude of "nodes" in /dev/ that are interfaces to almost all the devices on your computer. For example, /dev/hda or /dev/sda would refer to the first hard drive in your system (hda vs sda depends on the hard drive), and /dev/hda1 would refer to the first partition on your hard drive.
The most straight forward way to make a raw image of your partitions is to use dd to dump the entire partition to a single file (remember the OS access the partitions /dev/sda1 through a file interface). Make sure you are on a larger partition or on a secondary drive and perform the following command:
You can use the exact same command to back up the entire hard disk (replace hda1 with hda). You can then use any compression program (gunzip, zip, bzip) to compress the file for storage. You can use this same technique to make rote copies of entire partitions to make clones of your computer.
There is one limitation though, when restoring the backup: The partition needs to be the same size (or bigger) as the partition you took the image from, so this limits your options in case of a restore. However, you can always expand the partition after you've restored the backup using gparted or parted. The picture gets even muddier when you are trying to restore entire disk copies. However, if you are restoring the backup to the same exact hard drive, you don't need to worry about this at all.
