Network Boot/IBM/USB

By raraschek ·
I have a specific problem.
I have an IBM PC, without floppy, without DVDROM. My XP SP3 is acting weird, I want to install WIN 7. Update is not possible, I have to install it from DOS. I know how to do that, but WIN 7 can?t squeeze to a CD:)
My question is if I could boot from a NAS in DOS and install WIN 7 from the NAS. I tried to boot from SD card, but seems DOS does not recognize it as bootable.thank you

for a start it isn't being detected. At the DiskPart prompt type RESCAN

It will search the computer for newly-installed disks and volumes.


Try rebooting the computer without any USB devices attached. Then plug in the USB drive, right click on My Computer, select manage, and then click ?Disk Management.? If the drive is not present in the Disk Management window or if you are not able to access it, then the drive may have failed. In this window you should see all of your connected physical drives, their format, if they are healthy, and the drive letter.

Change the drive letter of the drive. Right-click on the drive in the list, and from the resulting menu select "Change Drive Letters and Paths"

Click on Change so you can change the drive letter. Click Change. Select a new drive letter from the drop down list, preferably the one that is not normally used for this drive.

Click Yes on the confirmation screen and you are done.


Write down all fixed Disk and CD/DVD drive letters so as not to delete them. DO NOT delete any of the fixed hard disk drives or CD/DVD optical drives registry values.

1. Login with Administrative privileges.

2. Disconnect all USB or FireWire storage devices.

3. Open Registry Editor by typing regedt32 in the Run box and navigate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. Right click on MountedDevices and select Export. Save this file as you may need it in case something goes wrong. Save it as Devices.reg, it should default to My Documents.

4. Under HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices there will be registry keys with the name that resembles the format of \DosDevice\X: where X can be any alphabet letter which corresponding to your physical system drive letter.

5. Delete all possible USB drives, FireWire drives and external drives which have a drive letter.

<b>DO NOT delete any of the fixed Hard Disk Drives or CD/DVD optical drives registry values.</b>

Exclude \DosDevice\A: which normally reserved for floppy disk drives.

The USB specification for a USB port is 500mA per port. If a device needs more then 500mA, the USB port may be switched off by the over current circuit.

To avoid too high a power consumption on the used USB port, connect the External USB device to a second USB port with the additional Power cable . This provides up to 1000mA to the USB device. If the device still fails, try a self-powered USB Hub, as they are, in most cases, able to provide more than 500mA per USB port.

i?m using IBM PC Intellistation M 6225 16G.

The USB device is a simple SD card reader with a SD card.

the USB drive is connected in Device Management,
but in the DISKPART nothing except the harddrive appears, even after the rescan, reboot, unplug....
