Nidaamka qalliinka lama bootin karo sababtoo ah nidaamka muhiimka ah ee khaladaadka darawalka^{(The operating system cannot be booted because of important system driver errors)} fariinta ayaa soo baxaysa haddii nidaamku awoodi waayo inuu si caadi ah u bootiyo. Mid ka mid ah faylkaas oo keeni kara qaladkan waa qevbda.sys . Faylkan waxa uu ku yaalaa \%Windir%\%System%\drivers\ , waxana uu la xidhiidhaa sheyga QLogic FastLinQ Ethernet ee ay samaysay Cavium , Inc/QLogic Corporation . Boostadani waxay ku siinaysaa xalalka ugu habboon ee aad isku dayi karto inaad si guul leh u hagaajiso qevbda.sys qaladka wakhtiga boot ee Windows 10 .

Fariinta qaladka waxaa sida caadiga ah la socda lambarka qaladka 0xc0000221 sida ka muuqata sawirka kore.

Nidaamka qalliinka lama bootin karo sababtoo ah khaladaadka darawalka ee nidaamka muhiimka ah

Haddii aad la kulanto arrintan, waxaad isku dayi kartaa xalalkayaga hoos ku qoran oo aan si gaar ah u kala horrayn oo arag haddii ay taasi caawinayso xallinta arrinta.

1. Hubi^(Check) aaladaha dibadda ku xiran ee arrinta
2. Samee iskaanka SFC
3. Tirtir darawalka khaldan
4. Samee Dayactirka Bilawga Tooska ah
5. Samee Soo Celinta Nidaamka

Aynu eegno sharraxaadda habka ay khusayso mid kasta oo ka mid ah xalalka taxan.

1] Hubi^(Check) aaladaha dibadda ku xiran ee arrinta

Khaladkan wakhtiga boot waxa uu ku dhici karaa iyada oo ay ugu wacan tahay qalab durugsan oo khaldan sida kiiboodhkaga dibadda, mouse-ka, wadida adag ee dibadda, USB Hub iwm.

Waxa aad ku ogaan kartaa adiga oo mid mid ka furaya dhammaan aaladaha dibadda ee ku xidhan oo haddii aad hesho qalab khaldan, ku xidh kombuyuutar kale oo arag haddii uu garanayo aaladda isaga oo aan cilad lahayn – haddii kale, waxa laga yaabaa in aad u baahato in aad gacanta ku rakibto darawal ku habboon qalabka. . Waxaad sidaas ku samayn kartaa adiga oo ku dhejinaya Habka Badbaadada^{(booting into Safe Mode)} ah oo ama isku day inaad gacanta ku cusboonaysiiso darawaladaada adoo isticmaalaya Maareeyaha Aaladda^{(updating your drivers manually via the Device Manager)} , ama waxaad heli kartaa cusboonaysiinta darawalka^{(get the driver updates on the Optional Updates)} qaybta Cusbooneysiinta Ikhtiyaarka ee hoos timaada Windows Update . Waxa kale  oo aad ka soo dejisan kartaa nooca ugu dambeeyay ee darawalka^{(download the latest version of the driver)} bogga soo saaraha qalabka.

Haddii ka dib cusboonaysiinta darawalka oo arrintu sii socoto, soo deji oo ku rakib nooca hore ee darawalka ee qalabka oo arag haddii ay taasi caawineyso.

2] Samee iskaanka SFC

Xalkani wuxuu kaaga baahan yahay inaad ku socodsiiso Checker File System ee Habka Badbaado, Wakhtiga Bootka ama Khadka Tooska ah oo arag haddii ay taasi ku caawinayso.

3] Tirtir darawalka khaldan

Si aad tan u samayso, waxaad u baahan tahay inaad gasho Advanced Recovery Options^{(boot into Advanced Recovery Options)} oo aad gasho Command Prompt.

Daaqadda degdegga ah ee amarka, ku qor amarka hoose oo ku dhufo Enter ka dib sadar kasta:

cd..
cd windows\system32
del netqevbda.inf

Sidoo kale isticmaal tillaabooyinka kore si aad sidoo kale u tirtirto qevbd.inf . Marka hore samee nidaamka soo celinta barta , kana taxaddar markaad isticmaasho amarka kore. Si sax ah ugu qor.

Haddii ay tahay darawal kale, waa inaad isticmaashaa magaca faylka darawalka.

4] Samee Dayactir Bilow Toos ah

Xalkani wuxuu kaaga baahan yahay inaad samayso Dayactir Bilow Toos ah^{(perform Automatic Startup Repair)} oo aad aragto haddii ay taasi ku caawinayso.

5] Samee Nidaamka Soo Celinta

Haddii mid ka mid ah xalalka kor ku xusan aysan kuu shaqeyn, waxaad ku soo celin kartaa nidaamkaaga meel hore . Si aad u qabato hawlgalkan, waxaad geli kartaa Habka^(Mode) Badbaadada ah ama waxaad geli kartaa Nidaamka Soo Celinta^{(System Restore)} Doorashada ee Deegaanka Soo-kabashada .

Waxaan rajeynayaa in tani ay ku caawineyso!

The operating system cannot be booted because of system driver errors

The operating system cannot be booted because of important system driver errors message appears if the system is unable to boot normally. One such file that can cause this error is qevbda.sys. This file is located in \%Windir%\%System%\drivers\, and it’s associated with the product QLogic FastLinQ Ethernet manufactured by Cavium, Inc/QLogic Corporation. This post provides the most suitable solutions you can try to successfully fix the qevbda.sys boot time error in Windows 10.

The error message is normally accompanied by the error code 0xc0000221 as shown in the image above.

The operating system cannot be booted because of important system driver errors

If you’re faced with this issue, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue.

1. Check connected external devices for issue
2. Run SFC scan
3. Delete faulty driver
4. Perform Automatic Startup Repair
5. Perform System Restore

Let’s take a look at the description of the process involved concerning each of the listed solutions.

1] Check connected external devices for issue

This boot time error can occur due to a malfunctioning peripheral device like your external keyboard, mouse, external hard drive, USB Hub etc.

You can diagnose by unplugging all connected external devices one by one and if you find a faulty device, connect it to any other computer and see if it recognizes the device without malfunctioning – otherwise, you may need to install a compatible driver for the device manually. You can do so by booting into Safe Mode and either try updating your drivers manually via the Device Manager, or you can get the driver updates on the Optional Updates section under Windows Update. You may also download the latest version of the driver from the device manufacturer’s website.

If after the driver update and the issue persists, download and install the earlier version of the driver for the device and see if that helps.

2] Run SFC scan

This solution requires you to run System File Checker in Safe Mode, Boot Time or Offline and see if that helps.

3] Delete the faulty driver

To do this, you need to boot into Advanced Recovery Options and access the Command Prompt.

In the command prompt window, type the command below and hit Enter after each line:

cd..
cd windows\system32
del netqevbda.inf

Also use the steps above to delete qevbd.inf as well. Create a system restore point first, and be careful when you use the above command. Type them correctly.

If it is some other driver, you have to use the name of that driver’s file.

4] Perform Automatic Startup Repair

This solution requires you to perform Automatic Startup Repair and see if that helps.

5] Perform System Restore

If none of the above solutions worked for you, you can restore your system to an earlier point. To perform this operation, you can boot into Safe Mode or access System Restore option in the Recovery Environment.

Hope this helps!
