Easy2Boot vs Ultimate Boot CD

Easy2Boot creates a multiboot USB drive for starting operating system installers, live systems and utilities. It runs on Linux and Windows, and the download includes three menu systems based on grub4dos, grubfm and Ventoy. Users add payloads by copying ISO, IMG and VHD files to the USB drive; listed payloads include Windows and Linux images, DOS programs and floppy images. For supported UEFI payloads, .imgPTN partition images can be used for Secure Boot. Easy2Boot can automate Windows installations with drivers, software, configuration, scripts and updates. Linux setup calls for an MBR partition layout and requires partition 4 to remain unused. The download guidance recommends a USB drive between 8GB and 2TB; larger drives may use 4K sectors or lack legacy boot support. Direct Secure UEFI32 booting to the agFM menu is not supported. The menu system uses open-source components and plain-text scripts, but the download also includes closed-source Windows utilities. Easy2Boot is free to use, but not for resale. Support options include a forum, live developer help, eBooks and online chat.

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.
