Official MediCat USB - A Multiboot Linux USB for PC Repair

[Jayro]

Can you add Cisco TeslaCrypt? It's a free tool used to decrypt files locked by ransomwares. Can you add Shadow Explorer too?

I couldn't get either of these working under WinPE, so they won't be included in my release, but feel free to add them in if you can get them working.

However, Unstoppable Copier, Autoruns, and NirLauncher all made the cut.

Still I couldn't find a way to integrate Kaspersky's Rescue Disk 10. Can you help me?

I'm quite busy today, but later tonight I'll try to test it out.

Are you using GFX Boot menu in the April release? I have been trying to get it to work without having to entirely rebuild the multiboot layout.

Made a new background for the v4.23.2016 April release:

What do you mean by GFX Boot? Upon booting up, it should show a black screen with a MedCat logo for a few seconds, then take you to the main menu, pictured in the screenshots on page 1.

 

[Shoshi]

No, I was talking about an extension to grub4dos that allows fancier menus and animations. http://diddy.boot-land.net/grub4dos/files/gfxmenu.htm

 

[Jayro]

That looks really interesting to me, I'm diving into that when I get home from work!

 

[Shoshi]

I like it as well, I just wish it was easier to create and edit.

 

[Shoshi]

I think I got Kapersky working. I also have text based Ubuntu installers working too!

 

[Jayro]

Cool! You can post your code here for others if you wish.

So I decided to go fresh and use another USB layout and it works there. But before I decided to change it up, I kludged together a setup that works on your MediCat layout with some mods. This utilizes code that WinSetupFromUSB makes but I edited it.

In antivirus.cfg I have my KAV entry like this

label KAV test
menu label title KAV test
KERNEL /boot/grub.exe
APPEND --config-file=/multiboot/menu.lst
#end kav

In the multiboot folder menu.lst which can be called anything because it is just a config file, the KAV code looks like this.

map --unmap=0:0xff
map --unhook && map --rehook
cat --hex --locate=PoLPu@ (md)0x3D0+0x130 > nul && echo Cannot continue if PLoP is active, please start this entry without loading PLoP first && echo && pause Press any key to return to the main menu && configfile /menu.lst
set /a dev=*0x8280&0xff
root (%dev%,0)
set ISO=/ISO/kav_rescue_10.iso
ls %ISO% > nul || find --set-root --devices=hf /usbdrive.tag|| echo Error! Could not find usbdrive.tag && echo  && pause Press any key to return to the main menu && configfile /menu.lst
ls %ISO% > nul || find --set-root --devices=hf %ISO% || echo Error! Could not find %ISO% && echo  && pause Press any key to return to the main menu && configfile /menu.lst
map %ISO% (0xff) || map --heads=0 --sectors-per-track=0 %ISO% (0xff) || echo FATAL ERROR mapping %ISO%, please check if file is present and defragmented && pause Press any key to return to main menu && configfile /menu.lst
#http://reboot.pro/topic/9916-grub4dos-isohybrided/page-2#entry88531
#http://www.rmprepusb.com/tutorials/tails
set /a dev=*0x82a0&0xff
debug 1
parttype (%dev%,3) | set check=
debug off
set check=%check:~-5,4%
if "%check%"=="0x00" partnew (%dev%,3) 0 0 0 && partnew (%dev%,3) 0x00 %ISO%
if not "%check%"=="0x00" echo WARNING: PARTITION TABLE 4 IN BIOS DEVICE %dev% IS ALREADY IN USE! && echo  && echo To prevent possible data loss will not continue further && pause && configfile /menu.lst
map --rehook
root (0xff)
chainloader (0xff)

That code is similar to what WinSetupFromUSB makes as I stated earlier.

That's some good work there @Shoshi, nice job!




I have a few important notes to share about the upcoming release:

==> It's going to be a hefty one, weighing in at around 4.3GB for the full MediCat DVD ISO, and between 2.2GB (32-bit) and 2.5GB (64-bit) for the Mini Windows 10 ISOs.

==> The full MediCat DVD ISO will require an 8GB USB flash drive, minimum (Unless you mod the ISO first).

==> The Mini Windows 10 ISOs will require 2GB of system RAM and a 4GB USB flash drive, minimum.

==> Rufus has been updated to v2.7, and is already in the Downloads folder.

==> I might release a beta, still undecided. If I do, it will only be a bug hunt; No additional features will be added after the beta. So far, I haven't run into any major show-stopping issues.

==> One small known issue I have found is Comodo Antivirus only seems to boot into text mode from USB. I may try the flat file method as a work-around, more testing is needed.



Other thoughts:
I tried my hardest to keep the main ISO under 3.99GB, but even with shrinking the Windows Recovery Disc's .wim files, it only shaved off a few Megabytes each. However, you can always remove some PortableApps to make it fit the 3.99GB mark if you desire. The Main ISO will never exceed 4.3GB though, so it will always fit a regular cheap DVD-R.

And as always, thank you all for your suggestions and help. Together we are shaping MediCat DVD to become the best damn Hiren's replacement on the web!

Is there any way you could test adding parted magic back in, because when I attempted to do so, it couldn't find the sqfs file for pmagic

 

[Shoshi]

I have been working on a new multiboot layout wich uses Grub4Dos and gfxmenu and it seems to work on a USB drive just fine. Much faster than using Ultraiso to make changes to an iso image and then test that way,. It works on USB and it looks like this.

When I put it into a bootable ISO it loads the menu just fine. But when I select to launch one of the antivirus rescue cd's I get this.

@Jayro I do apologize about taking over your thread. Does anyone have any ideas?

People are finding PartedMagic runs successfully from a folder named "pmagic" on the root of the DVD, flat-file method. As for me, I've run out of space on the disc, and Lubuntu already has the latest Gparted 0.25.0-3 built-in. And once PartedMagic became a forced paywall donation, I had no other choice but to drop it. The price of $5 has now nearly doubled to $9, or $49 for a year subscription. Ridiculous:

Are you using something like Sardu or Yumi to make the USB, or just building off of MediCat?

 

[Shoshi]

I tried all sorts of tools at first but none worked that great for all of the tools I wanted to package. So I started basing it on MediCat. After a while I decided I wanted to use GFXboot and I could not get it to work with yours so I started again basing i off the ISO that Winbuilder makes. Winbuilder has a plugin for for other os multiboot. Sadly the packaged ISO would not correctly mutiboot Bitdefender, ESET, etc. But I ended up using that ISO s the basis.

Why is it called MINI Windows 10? Is it the normal Pro version of W10 or what? I'm confused. I guess its not "cracked" but can you input your own Windows 10 key, right? The FAQ didn't really help me, only confused me more.

It's not a full installable version of Windows. It just runs live and is mainly used for troubleshooting. There is no way to add a Windows key and no need.

mini windows 10? how?
