Active@ Boot Disk Creator helps you prepare a bootable CD/DVD/Blu-ray or USB Flash mass storage device that you can use to start a machine with a damaged hard drive and recover data, recover partitions, wipe or erase data, create a disk image or repair security access issues.
To continue the train of reviews on software developed by LSoft Technologies Inc., I'll be reviewing one of their core products: Active@ Boot Disk. What this software proves itself to be is a powerful disk utility tool that allows the user to create a portable, working bootable disk that...
The Bootable Disk Creator (BootableDiscCreator.exe) is a program which creates a bootable floppy disk or USB drive with a registered copy of Active@ Password Changer saved on it.
Using this bootable disk you can run/install Active@ Password Changer on other computers.
All previous data stored on the floppy drive / USB drive will be deleted while creating the bootable disk.
Just insert the created bootable floppy drive / USB drive / CDROM into your computer and reboot.
Your computer BIOS settings will need to be changed to re-boot the computer using a bootable floppy / USB drive / CDROM.
The following steps are in continuation of the installation process for Active@ Password Changer.
If you intend to create a bootable disk, select the 'Run Bootable Disk Creator' option and click the [Finish] button to finish the installation process and to start the Bootable Disk Creation process.
The following screen is displayed upon successful completion of disk creation. The bootable disk contains the Active@ Password Changer installation files and USB/CD-ROM support files if selected.
Just a note to let you know that after a catastrophic failure of my XP machine, I was able to create a boot disk on my Windows 7 machine and successfully restore the complete drive from a previous backup on an external drive. Great program! Thanks very much.
One can write them by hand. Usually however such .mount and .swap unit files are automatically generated by programs known as generators. Two such generators are systemd-fstab-generator and systemd-gpt-auto-generator. They both run early in the bootstrap process and in response to a systemctl daemon-reload command, and (as you can see above) they generate a whole load of unit files into an undocumented subdirectory in /run/systemd/. systemd itself just uses those generated unit files.
But the systemd people have this idea of operating systems that auto configure themselves from a largely empty /etc tree, so-called stateless systems, and that is what mechanisms like the generator that reads the EFI partition table are all about. In the systemd people's plan, there is no /etc/fstab, and indeed is no persistent configuration data under /etc at all, and all of this stuff is deduced from the contents of the partition table on disc, at every bootstrap and at every systemctl daemon-reload. They are nowadays promoting operating system installer programs than do not write an /etc/fstab.
I can boot into Windows 10 from the SSD without any apparent issues, however the other disk (the original source drive) is offline. Computer Management's Storage section displays the following tooltip for the offline disk:
Is the SSD okay considering it's had its disk signature replaced with that of the old disk? Research suggests that it should be fine, and indeed that the destination ssd's drive signature would need to have been changed in order for me to boot from the cloned Windows installation, but because I lack knowledge in this area, I am uncertain whether or not this assumption is correct.
Also, just in case I want to boot from the old disk, but still see the SSD in Windows (and vice versa), what would be the best way to go about updating the disk signature of either the old hard drive or the new SSD (so that I can boot from either drive and also be able to see both drives no matter which one I choose to boot from)?
Open a command prompt (cmd.exe) as administrator. Type:
diskpart and hit ENTER after each command;
the prompt changes to DISKPART>
list disk to get a list all mounted physical disks.
Now, type select disk xy, e.g. select disk 1.
after the disk is selected, type:
uniqueid disk to show the signature of the disk.
To learn more, type help uniqueid disk
To change the signature, type:uniqueid disk ID=NEWSIGNATURE
(I suggest to increasing or decreasing the (hexadecimal) id by 1, [1-9A-F])
Finally, type exit, then reboot.
diskpart has two different commands. set id and uniqueid, if you clone a disk you want both of these ids to be the same because it is intended you are replacing one disk by physically removing it from the system. I would think you simply remove the sata cable connection to one of the two disks since you should be able to boot from whichever is connected to the proper sata port. diskpart also shows with the detail command the route to the disk you are using. for WHAT ITS WORTH. If you are looking for identical it may not be possible since the disk itself may have read only memory with a serial number imbedded within. Its all quite alimentary my dear Watson.
This document explains how to create a virtual machine (VM) instance by using aboot disk image, a boot disk snapshot, or a container image. Someimages supportShielded VM features, whichoffer security features such as UEFI-compliant firmware, Secure Boot, andvTPM-protected Measured Boot.On Shielded VMs, vTPM and integritymonitoring are enabled by default.
Copy the generated Capsule payload in step 2 to the EFI/UpdateCapsule directory in the esp partition of the active boot media.Refer to the step 1 in Manually Triggering the Capsule Update for more information.
Active Boot Disk contains a collection of powerful utilities to perform data recovery, data imaging, secure data erasure and a number of other tasks all from a bootable CD/DVD or USB flash media. The self-contained boot environment by-passes the operating system allowing you to boot previously unbootable PCs.
Active Boot Disk can be installed on a CD, DVD or USB flash drive which you can use to boot up your computer from. It provides a completely self-contained boot environment which bypasses the operating system entirely, allowing you to boot up on any computer, regardless of the condition of your Windows operating system.
You can install Active@ Boot Disk (recovery boot disk) to any kind of bootable media and then change your BIOS boot priority settings accordingly. Once the computer has started up from the bootable disk, you can safely remove it. Dual-boot functionality with DOS and Windows support is also possible with optical media.
Active@ Boot Disk for Windows XP/Vista/7/8/10 provides a full range of disk utilities for data recovery, secure erasure, disk imaging. You can use it to boot up otherwise unworkable computers to access your data and troubleshoot problems with ease.
Active Boot Disk is a boot CD/DVD/USB disk creator with a collection of useful utilities for system recovery purposes.
Active@ Boot Disk provides an impressive range of utilities for your hard disk and other storage devices. Using this software, you can create a fully bootable operating environment allowing you to start up your computer from a CD, DVD or USB flash drive even if your operating system is damaged and completely refuses to start. The independent boot environment means that it does not rely on the contents or state of your hard disk.
Main Partition Active specifies whether to mark the partition as active. On a BIOS-based system, the active partition is the partition the system will boot to. This partition must be a primary partition. On a Unified Extensible Firmware Interface (UEFI)-based system, this setting is not used. The system will always boot to the EFI System Partition (ESP). If Active is set for this partition type, it is ignored. Only one active partition can be set on a hard disk. If an active partition already exists on the disk when this setting is changed to true, the existing active setting is removed and the selected partition is marked as active. Only primary partitions can be marked as active. If Active is set for other partition types, the setting is ignored.
The syslinux-install_update script will install the bootloader code (usually to the VBR), copy *.c32 modules to /boot/syslinux/, set the boot flag and install the boot code in the MBR. It can handle MBR and GPT disks along with software RAID:
For an MBR partition table, ensure your boot partition is marked as "active" in your partition table (the "boot" flag is set). Applications capable of doing this include fdisk and parted. It should look like this:
If booting a btrfs subvolume, amend the APPEND line with rootflags=subvol=root_subvolume. For example, where /dev/disk/by-uuid/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX has been mounted as a btrfs subvolume called 'ROOT' (e.g. mount -o noatime,subvol=ROOT /dev/disk/by-uuid/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX /mnt), then the APPEND line would need to be modified as follows:
and then boot up with the Arch install disk. Next, use cfdisk to delete the /boot partition, and recreate it. This time it should begin at the proper sector, 63. Now mount your partitions and chroot into your mounted system, as described in the installation guide. Restore /boot with the command
The MBR that comes with Syslinux looks for the first active partition that has the boot flag set. The Windows partition was likely found first and had the boot flag set. If you wanted, you could use the MBR that Windows or MS-DOS fdisk provides.
