I downloaded windows 7 professional COEM version from official links provided by Microsoft. Filename Win7_Pro_SP1_English_COEM_x64.iso 32 bit version works fine. 64 bit one is corrupted. I have tried any possible method of installing. Wipe hdd before installation, dvd, usb, vmware etc. No success at all. Also downloaded it 3 times. Still the same issue. After it copies the files it shows this error
used MD5_and_SHA_Checksum_Utility MD5 Checksum: 109A4F4CFB91542C8AE2526C7C83A088 SHA-1 Checksum: 13CD108AE4EE3479B8FED9AC19EF1957B237C902 SHA-256 Checksum: 8AA996E32C704622CBDAB518C9B2D91D092A4502FA787A5EAE7221ACF6E2F7CA SHA-512 Checksum: 42EF923F48F433812B7383DA007BD798E69083E132B8D75C6DB1E6B0817642A8CA07E955141F98B8EFA080A2C0EB3C3E38A33DEFB8B52D3BB90180F924C5AD85
Plz write your checksums using the same software i used so i can compare it when i download. Thnx MD5_and_SHA_Checksum_Utility
Tried 2 different pc. same problem. also tried vmware. 32 bit version installs fine. i dont think its a hardware problem
Why should i use the same software? The result of any checksum verifying software should give the same result, as you can see your SHA-1 and SHA-256 checksums don't match the one i gave. Did you re-download the iso from my official MSFT/MSDN url?
i am downloading it. my net is slow. need some time, if checkums still dont match with yours what it means?
first i tried installing from dvd. i used clonecd to burn, 32bit worked ok using dvd and using vmware. 64 bit wont work in neither way. tried clonecd, img burner, default windows iso burner. no success. used powerido do write it at usb. usually when other software fails writing iso at usb poweriso never failed. before you gave me the link i was redownloading the iso image from microsoft official. new iso checkums are: MD5 Checksum: 39134FAD6CCC6292A5E81A5DCEDC4D13 SHA-1 Checksum: 5998495086FDE086B2C8A1E490D8F1CD1DCC99CC SHA-256 Checksum: 8341417C575ADB92CD11A1F77666B6D6CBBCFC56855927407235983E838CFE83 SHA-512 Checksum: 98BDC85AFA91CB34F70C8FCC0E00644D548C438AB235A39ED0BF08A0B2C1C44376FAC4B2A4D70557746C4C3BAB68726617F82589B85C8F356768868A1970EB06 Now im whaiting for your link to finish downloading and ill check checkums. also im testing this new iso in vmware. ill post results when install finishes.
This iso (you now show) has the correct checksums. TIP: To create a bootable USB installmedium you only have to format it FAT32 and extract the iso to it.
thank you. im testing it in vmware. can you plz also verify my 32bit checkums. after installing fresh windows 360 total secirity found a tempered windows system file during scan 32 bit checkums. MD5 Checksum: 296F892E1F9B66EF5836A54557309E94 SHA-1 Checksum: A908CF84FD448C235945FB5B6E2FF232EB362575 SHA-256 Checksum: F814B85295351E4AB902DC1777C5539F6D855C8997BEA833277290BCA0A5385B SHA-512 Checksum: 7DFEF88ADE46FCED926FCC5F05B21DA8F60326E7984A2166AB2F2D2770D82A40BD46E1A3FC704C2973CB406B2C6F98F91830C48C9E23361CF37B34851E97A939
These are the checksums: Code: --------------------------- Checksum information --------------------------- Name: Win7_Pro_SP1_English_COEM_x32.iso Size: 2564476928 bytes (2445 MB) CRC32: 3D0310E8 CRC64: 229B2B0586FF23A4 SHA256: F814B85295351E4AB902DC1777C5539F6D855C8997BEA833277290BCA0A5385B SHA1: A908CF84FD448C235945FB5B6E2FF232EB362575 BLAKE2sp: 7B3F8BA5D3AE7723F857C501473534650C4071313F36F0ABB34EDDE4E0308FFF --------------------------- OK --------------------------- They match.
what software you use for checkums. it shows ok in the end. does it automatically tell if windows iso is legit?
new downloaded iso seems to be fine. installing is progresing in vmware. weird because 3 first downloads were not working. i think i have a malware activity in my network. one day even my 2 android smartphones keep force rebooting. oneplus one and note 3. it happened almost at the same time. i may be wrong but idk
