Title looking at a rap, particular case is this: the recent preparation made system installation disk, U disk to install Windows 7 computer with 64 SP1 system, OptiPlex 5040 dell desktops in a series of puzzling problem, based on the spirit of trivial pursuit, specially in the MSDN professional BBS registered post, I ask you a great god, hoping to find the feasible solution, more hope to have the technology and can explain the cause of the problem from the technical level, thank you,

1, I made the system installation UltraISO U disk (way of writing is the USB HDD +), USB interface is sandisk 2.0 8 g plate, system installation image tried two, one is the extract of dell installation disk ISO, another is in the MSDN download cn_windows_7_ultimate_with_sp1_x64_dvd_u_677408. ISO (don't and I said I use Windows 7 - USB - DVD - do USB installation tool, this tool is made to the U disk on the dell 5040 get in the installation interface at all, but on my other computer assembly can, estimation is and is not compatible with the reason of dell computers),

2, set up the computer usb startup, from U disk boot into installation interface, here tried Legacy and UEFI two modes, will face the following problems,

After 3, click the "install now", "lack of required CD/DVD drive device driver", after this problem, on the Internet to find a lot of solutions, such as
(1) the U disk pulled the plug, 11 results before and after the computer USB interface insert a times also not line,
(2) try again change a usb stick, this one I tried another Sandisk 3.0 interface 16 g plate and electric interface 3.0 32 g plate, all not line,

4, here is the key point of this post: through the experiment on different computers, the above questions are the same, but in my assembly machine, I can find a 100% of the solution, is to prompt "lacks the CD/DVD drive device driver", press Shift + F10 into the command prompt interface, use the CD command sources folder into the U disk, and then execute the setup. Exe command, can normal installation system, but this method on the dell 5040 desktop can't use, because the prompt "lacks the CD/DVD drive device driver", use the command prompt list disk command, and the interface on the "browse" button, and cannot see my U disk, can only see on a computer hard drive, insert U disk to pull out the N times, in all of the USB interface, can identify, I under the "browse" interface Intel USB 3.0 driver installation, complete the USB mouse and keyboard directly after losing reaction, can only be mandatory shutdown restart,
So I want to ask is why will appear this problem? How can I identify my U disk in this installation interface?

You this kind of situation the reason to say

But now U disk boot disk software usually has the option of a local mode, can try this one, and then put the mirror kao to the local disk to install

Can say about it, I am made of UltraISO startup disk, not local mode option, is to choose the U disk starts directly enter the system setup interface

CodePudding user response:

Baidu, the software has a local model, that is to say, don't even need the U disk loading system, just install the machine last week, but is worse than you, no matter how, is can't get into PE boot interface, finally USES the local model to solve the problem, so sometimes need to change the thinking to solve the problem, don't have to struggle, just like Bill Gates machine blue screen when making a presentation rather than to check the reason of the blue screen directly in machine

Ok, I'll try, thank you

In addition, you can technically analyze to appear the interface for installation can't find U disk is what reason, when I was in the BIOS setup the order is to be able to find U disk, can also be installed into the interface, the motherboard support U disk, why after installation into the interface and can't find U disk?

CodePudding user response:

When top, to the laptop installation system, I also often encountered, although can use PE installation, but still want to understand the reasons for this problem

CodePudding user response:

Can change a U disk production startup disk, such as the same; May be the problem you made

CodePudding user response:

refer to the eighth floor garry7 response:

can change a U disk production startup disk, such as the same; May be the problem you made

Successively with the 4 U disk, sandisk 2.0 interface 8 g, sandisk 3.0 interface 16 g, electric interface 32 g, 3.0 PNY, 2.0 interface 4 g,
The first three dish can't, use WindowsImageTool processing also useless,
PNY, interface of 4 g usb 2.0 made startup disk is also deny ultraISO directly, and then use the gigabyte WindowsImageTool processing, and then enter the installation interface after finally can use the list disk command to see U disk, it seems this problem and U disk master, usb interface type have relations? Or master also determines the usb interface type, so essentially just with U disk master compatibility?

In addition, with this solution is just the list disk command to find u disk, but click on the "install now" will be prompted to "lacks the CD/DVD drive device driver", this problem still don't know why, can't find 100% can direct solution,

It may be your image file has a problem

CodePudding user response:

My mirror from dell computers bring to install dish using ultraiso copy, one from the MSDN download, and made the MD5 check, should be no problem, and I found that there are a lot of people in baidu search encountered similar problems, but the solutions are not perfect, no one can analysis from the perspective of technical reason, or from the ribs on the solution to this problem are given,

that may be you is a problem with the image file

It may be your computer problems?

CodePudding user response:

Install Windows 7 - USB - DVD - tool do U disk, the tool to the U disk on the dell 5040 never get in the installation interface, but on my other computer assembly can - whether to U disk only support UEFI installation, and in the original image, the lack of an efi file, copy to change name to boot directory

I like you, the same, the same didn't solve, in order to you, register a account,

CodePudding user response:

Encounter this kind of circumstance commonly use USB2.0 interface

CodePudding user response:

Agree with the upstairs moderator said, faced a similar situation before, didn't start to drive, seemed to see driver can be downloaded to the integration of PE,
