Bootable USB Test 1.2.0001
Before restarting your computer and booting from the USB, it's a good idea to check whether the drive works properly or not.
Bootable USB Test is a convenient method to test a bootable USB drive for bootup. It is easy to use, powerful and intuitive, does not require installation and it is small in size. Its most important advantage is that it enables you to check the USB drive without having to go through two system restarts.

- Creates virtual PC environment and boots up USB drive for test
- Locks USB drive from Windows and other apps to avoid writes from outside the simulation
- Redirects all writes to the USB inside the simulation to a temporary file (creates snapshot at simulation start)
- Creates temporary virtual hard drive for compatibility and better simulation of a real PC
- Compress virtual HDD to reduce it size almost to 0 and speed it creation up
- Can work both with flash and HDD drives connected by USB/SATA/IDE/SCSI/etc. bus
Download / Distribution path
Bootable USB Test app is already bundled with WinToFlash and can be downloaded separately from our web site.
Bootable USB Test is portable app, no installation required. Unzip and start emutest.exe. WinToFlash allows to start test inside itself.
To use Bootable USB Test your computer has to meet certain hardware requirements. Actual requirements vary, depending on the system configuration and the programs and features that you choose.
- Pentium 233-megahertz (MHz) processor or faster
- At least 64 megabytes (MB) of RAM
- At least 3,5 megabytes (MB) of available space on the hard disk
- Keyboard and a Microsoft Mouse or some other compatible pointing device
- Video adapter and monitor with Super VGA (800 x 600) or higher resolution
- Windows XP—10, 32 or 64 bit
- WOW64 subsystem enabled on 64 bit platforms
Bootable USB Test app doesn't require Microsoft .NET, Visual C++ Redistributable Packages and others to work.
NOTE: WOW64 subsystem is enabled on every 64 bit Windows installed, but may be disabled/removed in WinPE/recovery 64 bit environments.
Bootable USB Test uses x86 (i386) only QEMU emulator version 0.15.1
Bootable device or image selection
Select what do you want to test for bootup: USB device, ISO image or Floppy image.
Floppy image can't be compressed, i.e. IMZ is not supported.
All the connected USB drives are automatically detected and displayed in the top drop-down list. Bootable USB Test app shows a disk letter, interface type, the name of the device and its size too.
Enumerate USB devices only
Option available only for "USB or HDD" selection. It filters storage devices in the list to show only connected by USB bus. Uncheck it to enumerate internal HDDs or storage devices on non-USB buses like SCSI, IDE, SATA, etc too.
Memory size for virtual PC
Set how many physical memory can be used for emulation. Typical 512Mb is OK for most cases.
Don't save file changes
Bootable USB Test app creates a snapshot for virtual PC and redirects all write calls to USB into temporary file so USB device file system won't be affected.
Create temporary Virtual Hard Drive for session
For compatibility and better simulation of a real PC Bootable USB Test app creates an empty file with only 0s in it in the %temp% folder for emulation session. It deletes this file right after simulation ends.
Set Compressed NTFS attribute for Virtual Hard Drive file
Compressed attribute says NTFS to use compression with your Virtual Hard Drive file, and, because it contest only 0s, compressed size of Virtual Hard Drive file inside the %temp% folder will be ~0 instead of it real size. It's recommended to set this option every time you use Bootable USB Test app. This option works only for NTFS volumes and won't work on FAT.
Virtual Hard Drive size
Size of the Virtual Hard Drive inside the simulation.
