FalconFour’s Ultimate Boot CD/USB 4.6

March 31, 2013

Hola amigos. I don’t speak Spanish, but, you know, trying to stay hip. Like actually releasing a new version, that sounds like an awesome idea, doesn’t it? Hell, v4.5 had so many holes that’ve been fixed in v4.6, it made 4.5 look like Swiss cheese. And I’m sure the Swiss have even used this thing. It’s been all the way around the internet and back – in fact, v4.6 was created on a laptop I bought from a guy on eBay (just shopping around) that uses my disc as well! I was amazed. This thing has seen some mileage.

FalconFour's Ultimate Boot CD v4.6

In this boot CD are the most popular and useful tools anyone would ever need. The best of the free software, the best of the commercial software, and it all fits on one CD-R that’s readable by any computer worth booting on. Not everything can read a DVD, and USB booting is hit and miss at best.

Meanwhile, since the last release in 2011, more has changed. I wrote off the dry, stale corporate IT world of wastefulness and over-powered, under-utilized systems and unnecessary, poorly planned “cloud” services. Currently unemployed (at least, as of this release!), I found some time to put some major polish on MiniXP and get everything working well. Still would love to work in computer repair. Anyone? I’ll even move. Anything? Anyone? Bueller? Bueller?

This disc, an even more minor single-point revision, is actually a huge MiniXP update. Other tools have been updated, like Memtest86+, which has been replaced with the more frequently updated Memtest86, with a smarter loading mechanism. Tons of updates in MiniXP. AHCI support, for one thing. Better driver support for network and wireless drivers, faster (and more reliable) startup, better error reporting/catching, better graphics, better compatibility with more tools and software, and… Flash support in the latest Portable Firefox! Yes, you can watch YouTube from MiniXP now. And access TeamViewer/LogMeIn which uses Flash. LOTS of work has been put into polishing the startup routine and compatibility.f4ubcd-46-menu

Plenty of features from v4.5: Virtual Floppy enables you to mount images from a USB stick to be used in a boot selection like MiniXP (for F6 SATA/RAID drivers) or FreeDOS (Dell option). VFD with file copy allows you to make a <1mb RAR file accessible to DR-DOS or Hiren’s DOS in a virtual floppy. Wireless drivers in MiniXP along with improved Ethernet and storage support. Mini Linux provided by RIP Linux. Bootable partition and imaging utilities provided by Acronis True Image and EASEUS Partition Manager. Improved Memtest86+ with failsafe mode to resolve startup hangs. Kon-Boot 1.1 is really v1.1 now, with support for 32-bit and 64-bit Windows. Tons of new utilities in MiniXP with new launchers to provide easier access. ERD 5.0 is integrated with MiniXP for offline system restore and service/driver management, and Microsoft DaRT 6.5 (x86 and x64) are added to support Windows Vista and 7. Antivirus scanning with real-time updates is provided by DaRT 6.5’s Standalone System Sweeper, and allows you to load definitions to a USB stick for live updating.

This ain’t yo mama’s BartPE compilation.


Once you dive into this disc, you’ll never need another boot CD.

In this update

4.6, Apr-1-13: Many modifications to MiniXP. AHCI/RAID support (not quite universal yet due to architecture). Firefox update with Flash support. Memtest86 instead of Memtest86+. Streamlined boot menu configuration. Made USB setup easier with BootICE. ImageX front and center on the desktop now, as well as some additional new icons. Vastly improved MiniXP startup process. PDF, Word, Excel file viewing support. Replaced a billion references to outdated portable Opera browser in MiniXP with Firefox. Much improved network driver support. Battery support. Power management support (no longer roasts laptop CPUs while in MiniXP). Added keyboard switcher in tray. More sane date/time display.

Download the torrent (save bandwidth, help others download it too!)

Then grab the v4.61 Patch to get up to date.

Or download v4.61 directly via HTTP (be a freeloader! Or if you have trouble with the torrent!)

  1. Is anyone using F4UBCD with Easy2Boot? I’m able to boot into the MiniXP environment, but all of the utilities and tools are missing – I only have options for disk management, show drives, etc.

  2. Sorry if this is a dumb question, but where’s the guide to boot it from flashdrive?

    • Should be a “USB Instructions.txt” file in the torrent. Failing that, here’s the contents of that file:
      The process for making this into a bootable USB stick is much easier than in v4.5.

      Here’s the premise: there are two types of boot sectors that make something bootable:
      – An MBR (master boot record) is in the very first sector of the drive. Usually it just says “Boot the active partition’s PBR”. It contains a list of partitions, and points to the correct PBR to boot.
      – A PBR (partition boot record) is at the very start of the *partition* (not the disk) and contains the code that boots the system from that partition.

      A Flash drive (or other removable drive, e.g. an SD card) only has a PBR since it only contains one partition. To create an MBR (unnecessary), you would need to reformat the drive. You can get away with only using a PBR. Some Flash drives may be using an MBR as well – so we just need to check that.

      Here’s how you do it:

      (1) Use any flash drive. — YOU DO NOT HAVE TO REFORMAT IT. — NTFS or FAT32 will both work. FAT32 formatted with 16kb sectors is best for most Flash drives.
      (2) Extract the files from the ISO (do NOT copy the ISO itself) to your USB drive.
      — (You should have F4UBCD, HBCD, BOOT, etc. folders in the USB drive root.
      (3) On the USB drive, browse to HBCD\WinTools and run BootICE.cmd.
      (4) In BootICE, SELECT YOUR FLASH DRIVE (important!) and do the following:
      — Click “Process MBR”. If it indicates “Unknown”, skip this part. Otherwise, verify that it’s set to “Windows NT 5.x/6.x MBR”. Install it if needed. You can’t really mess this up.
      — Click “Process PBR”. It will usually say “Unknown” here, but if it says NTLDR or BOOTMGR, it’s been formatted by Windows to run the Windows boot loader. We need to change this to GRUB4DOS. Select GRUB4DOS and click “Install/Config”. Use the default options.
      — Click “Parts Manage”. If any partitions are shown here, you’ve got an MBR (that’s OK). Select the partition and make sure it’s Active – if it is, “Activate” will be greyed out. Click it if needed, and hit Close.

      You’re done! You’ve now got a bootable F4UBCD Flash drive. No external tools needed! :)

      • Thank you. :)

  3. Have you ever considered publishing an ebook or guest authoring on other blogs?
    I have a blog based upon on the same subjects you discuss and would really like
    to have you share some stories/information. I know my viewers would appreciate your work.
    If you’re even remotely interested, feel free to shoot
    me an e-mail.

  5. […] []).push({}); Geht noch F8 mit : sfc /scannow chkdsk /r c: ansonsten Live-Cd starten (zb. https://falconfour.wordpress.com/2013…b-v4-6-f4ubcd/) und damit die HDD, Ram […]

  6. What about checksums for the v4.61 direct download?

  7. Ahhh, I got it to work! I was having problems just getting this to install on my USB Stick but I got it worked out. I have not got to test everything yet because it was like 3AM when I finally got it working, I was able to boot up in it thats as far as I got! So far Nice Job! Today is a new day, cover me I am going in:)

    • I cannot get DaRT 6.5 to load. What can I do to fix this?

  8. I would also include GPU-Z; a year or 2 ago I came upon a desktop which had bad graphics performance (suddenly) and I looked for software problems (viruses & others). After a while I used CPU-Z to look into the system’s hardware but found no problem. It went on and on till I started up the latest GPU-Z and found that of the original RAM on the graphics card 3/4 was defective. I couldn’t believe that that card even worked anymore. Lesson: CPU-Z doesn’t check that RAM, GPU-Z checks it out and reports the correct amount of ‘working’ RAM on your graphics card(s)!

  9. Hi FalconFour! Ilove your stuff, but what’s going on? No new release since 2013, and what happened to Hiren? Pankaj? Proteus? They haven’t done anything since 2012. I hope to see more from you guys soon. Your Boot CD’s are a Godsend in the IT world. Thanks!

  10. I’m not able to use the current version of the boot cd with Rufus. It keeps telling me it’s an unsupported ISO.

  11. Tried to DL the Torrent but the link is broken. Sorry no saving the planet’s bandwidth tonight :-(

  12. :( Dropbox says your account sees too much action and I can’t get to the torrent download. Any alternative?

  13. Hi All,

    the Download links are not working:
    A) Dropbox torrent Fails,
    B) Patch Fails,

    Could you please update the Links in a way we can trust the Download?

    Thanks a lot for the GREAT WORK,

  14. Magnet link to torrent

  15. This CD has saved my sorry hide twice in the last month. Just wanted to say “Thanks.”

  16. Ok. Having a huge problem here. I’m trying to boot into Falcon Four boot cd (which works on other pc’s) but for some reason on my Laptop I’m getting an error message when starting up minixp
    which says lsass.exe “The application failed to initialize properly (0xc0000142). click OK to terminate the application”

    and then it just shuts off the laptop without even clicking on “ok”
    What issue is this?
    could this be from using ccleaner and if so How do I fix it so that that falcon boot cd will work?

  17. thank You for great tool. i looking for some remote desktop app and ftp server app. i tried teamviewer by it doenst work.
