『楼 主』:
谁知道USBOOT制作启动盘的秘密？
使用 LLM 解释/回答一下
USBOOT是一个非常有名、使用非常广泛的U盘启动盘制作工具，它的特点是兼容性好，很多软件只能对某些品牌的U盘有效，例如：HPUSBFW.EXE使用者也很多，但它对某些品牌不能识别，例如对市场常用的kingston不能识别，而USBOOT我至今尚未发现不能识别的U盘，而且它还有个很好的功能，能设计U盘的格式。这一点很好。
在时空论坛常有人反应grub4dos对某些品牌U盘USB-ZIP 格式支持不佳，但我一直未遇到此情况，因为我总是把U盘格式化成FDD格式，FDD 格式有很多好处，因为它启动后是A盘，不会影响硬盘分区盘符，这样不会影响原硬盘程序的运行，更为重要的是可避免因疏忽误认盘符，进行磁盘操作造成严重后果。
USBOOT对于2G的以下的U盘均可格式化成FDD格式，即均可启动成A盘，一般作启动、维护盘2G均够用了。2G以上格式成HDD，启动成C盘。如果格式成ZIP ，不同品牌的电脑启动后盘符可不同，我的intel机启动成A：，asus启动成C：。
现在问题是：
USBOOT制作启动盘后，U盘的分区全乱了，其它分区软件不能识别，看起来一团糟。windows或linux分区工具均看成乱七八糟的，四个主分区，磁盘容量全不对了，但奇怪的是：它不影响其正常使用！！！
如果把分区纠正，则不能正常使用，请高人分析其原理。
USBOOT is a very famous and widely used USB flash drive boot disk making tool. Its feature is good compatibility. Many software is only effective for certain brands of USB flash drives. For example, HPUSBFW.EXE is also used by many people, but it cannot recognize certain brands. For example, it cannot recognize Kingston which is commonly used in the market. And I have not found any USB flash drive that USBOOT cannot recognize so far, and it also has a very good function, which is to design the format of the USB flash drive. This is very good.
In the时空 Forum, people often report that grub4dos has poor support for certain brands of USB flash drives in USB-ZIP format, but I have never encountered this situation because I always format the USB flash drive to FDD format. The FDD format has many advantages. Because after booting, it is drive A, which will not affect the drive letter of the hard disk partition, so it will not affect the operation of the original hard disk program. More importantly, it can avoid serious consequences caused by disk operations due to misidentifying the drive letter due to negligence.
USBOOT can format USB flash drives below 2G into FDD format, that is, can all be booted into drive A. Generally, 2G is enough for making boot and maintenance disks. For those above 2G, format into HDD and boot into drive C. If formatted into ZIP, the drive letter after booting on computers of different brands can be different. My Intel machine boots into A:, and the Asus boots into C:.
Now the problem is:
After USBOOT makes the boot disk, the partitions of the USB flash drive are all messed up, and other partition software cannot recognize them, looking like a mess. Windows or Linux partition tools all see them as messy. There are four primary partitions, and the disk capacity is all wrong. But strangely, it does not affect its normal use!!!
If the partitions are corrected, it cannot be used normally. Please experts analyze the principle.
