Deepin Boot Maker vs Ultimate Boot CD

Deepin Boot Maker is a free, open-source utility from the deepin Community for creating a Deepin boot disk. The workflow is to choose an ISO image, select a USB disk, start creating the disk, and complete the process. It is designed for Deepin installation ISOs and also works with Ubuntu live installation ISOs; ISO files can be added by dragging and dropping them. The official download directory lists a Windows executable and a macOS ZIP archive. On Linux, Deepin users can install the program from the repository with `sudo apt-get install deepin-boot-maker`; the README says the only binary release is currently from a Deepin OS ISO. The project uses the GPL-3.0-only license and links to its source code. For usage help, it lists a wiki, forum, Developer Center, and Matrix. The project encourages issue reports and contributions. No paid plans or usage limits are stated.

Ultimate Boot CD (UBCD) gathers floppy-based diagnostic utilities into one bootable ISO. After starting from the CD, users choose a program from a text menu; that program runs from a virtual floppy created in memory. The collection includes stress, memory, disk-health, and GPU testing tools. The listed release is V5.3.9, described as a maintenance release while the project says it is largely in hibernation. UBCD does not support UEFI boot, and its download guidance recommends enabling CSM Boot on UEFI machines. USB-memory boot is described as experimental on supported hardware. The download page publishes MD5, SHA1, and SHA-256 checksums for the ISO and distributes it through P2P plus volunteer HTTP mirrors. Utilities include freeware, shareware, and open-license programs with differing terms; some freeware bars commercial redistribution. Instructions explain how to customize a disc. UBCD Live is a separate early-beta Debian-based rescue CD. The listed plan is a free 803 MB ISO download.
