用 WINDOWS 2000 安裝居然可以切割&&安裝..
現在正在安裝中..不知會不會裝好不能 RUN...

PS:我已經換過兩個版本的 XP 安裝光碟了 ...都是一樣狀況..
也拿到另外一台電腦上面試過..也是相同情形.. 都是XP 安裝光碟無法切割磁區的狀況..

用的是連鈺電子的外接盒.. 我試過兩種款式都是相同狀況...

答案是 NO

除非你買特別特殊的外接盒子特別表明有支援USB開機
通常都會給一張特殊的開機片/DRIVER...

唉..果然是NO..
開機開到一半..進入藍螢幕

出現 INACCESSIBLE_BOOT_DEVICE

有一種講法是傳輸太慢的錯誤

另一種講法..
At some point in its installation, a 32-bit operating system installs its own drivers in place of the older "INT 13h" drivers. Thus, at the moment an operating system decides to start using its own "native 32-bit" drivers instead of "INT 13h," the operating system must have enough of itself and its drivers loaded to begin to successfully read from a disk drive. However, current operating systems do not account for the possibility of the boot device being on the USB bus. In fact, by default, Windows 95, 98, ME, NT4, 2000, XP, and Linux only handle boot devices on the ATA/IDE bus, and certain SCSI busses. As a result, the most common result of trying to install or launch a 32-bit OS from a USB boot device is a blue screen with "INACCESSIBLE_BOOT_DEVICE" displayed.

Windows Requirements for Boot Devices
The best thing about adding another bootable bus to Windows is that manufacturers can take advantage of much of the existing Windows boot process. As long as a new device looks and behaves like existing devices while NT Loader loads the system, new devices can be made to work like old devices. The goal for booting Windows from a USB device is to use as much of the existing Windows boot process with as little change as possible.

This paper focuses solely on booting from hard disk drives and CD-ROM drives for recovery and deployment purposes. Windows as it exists today is currently not optimized to run as an installed operating system from USB attached mass-storage or CD.

The USB Mass Storage support consists of storage protocols over USB that enable USB hard disk drives and USB CD-ROM drives. All storage devices that are to be boot devices for Windows should behave like one of those two categories to take advantage of the existing boot process. DVD-ROM drives fit into the category of CD-ROM drives for the purpose of this document.

BIOS must support INT 13h During the boot process, Windows assumes that support for communicating with the boot device, either hard disk drive or CD-ROM drive, is present in INT 13h when Windows loads because the NT Loader uses calls to INT 13h to access the disk. INT 13h support must comply with the "BIOS Enhanced Disk Drive Services - 2" specification and the "USB Mass Storage Specification for Bootability," The newer specification is considered the authority if the two specifications contradict each other.

Accurate drive numbering by BIOS Windows also requires that the assignment of drive numbers follows "Compaq Phoenix Intel BIOS Boot Specification version 1.01." Hard disk drives should begin numbering at 80h and CD-ROM drives should begin numbering at 82h, as in the past.

In this paper, the remainder of the requirements, along with recommendations for component manufacturers, has been organized by the different components that play a part in booting.

資質不好..還是不太懂..

BIOS must support INT 13h During the boot process
應該是我們現在支援 USB 開機的 BIOS 都有支援是吧?

如果是上述的這個問題的話..奇怪. dos 模式怎能順利開機成功呢?

win2000 也不是不能開機..而是開到一半出現藍螢幕
INACCESSIBLE_BOOT_DEVICE

麻煩指點迷津

INT 13h 是其中一個要求
另外一個問題是在於 NT 系列系統方面

基本上
Win95/98/ME 都可以用USB開機
很多人都是用USB Flash Drive來跑95/98/ME

可是在安裝NT系列系統的時候
會有其它的問題發生
所以會變成無法在 Removeable Drive上面跑這類系統
除非有特別聲明可以支援USB開機
不然都是 NO

希望Windows Vista可以解決這個問題
不過......... 唉

可以TRY看看Linux..Knoppix

前陣子有做一個source是使用usb開機的，system 是win200，PC是IBM S51及A50
USB型號....我忘了
請先確認
1.pc有支援usb開機(沒有其它的就不用看囉)
2.usb有開機功能(應該都有了)
3.fdisk 後請確認你分割後的開機區確實有寫入
分割完執行fdsik /mbr
再進fdisk中看分割後的c:的lable有沒有顯示 "A"
4.HDD不於200G，大於200G會有其它的問題

M$的網頁上清清楚楚的寫著"Current versions of Windows should not be installed to USB hard disk drives because Windows does not support USB hard disk drives as the primary boot device.",該網頁所說的應該只是未來版本的Windows要自USB storage上boot時(如果M$決定支援的話,不過以鵝個人的看法M$不太可能支援----不是技術性的問題,純屬非技術性考量)所須注意的前提而已....
